Masterspace

UPDATE (temporary one untill i get more free time):
The game has been abandoned unfortunately (afaik if you have a bug the Dev still provides support though).
As it stands now, it is a nice voxel sandbox building game but there is really not much to do besides mining resources, building things and flying to other planets to.... build some more.
IMHO this is still better than some other abandoned EA games like Starforge unfortunately despite some nice ideas (like unusuall skill point system) it is clear that the game is missing the endgame.
In summary - i would still recommend this but only during sales (<5€)
EA review
______________________________________
A really nice game, recommended if you have a powerful PC (and no mainboard integrated graphic card).
- One of the better feeling game in the recent voxel dig/craft/build genre attack
+ feels more complete in comparison to games like Blockscape, StarForge, Xenominer, Vox, Realm Explorer
The good:
- as usuall -> lots of digging, searching for resources, building and crafting
- a well thought building system
- nice skill points system - the more you build the more points you get (to unlock skills/perks/cratfables)
- not bad graphic (compared to pixel voxel games)
- perks/skills to swim/build faster, etc. Also to unlock new crafting items.
- cool game modes in development
- build a spaceship and fly do another planet!
- cool water system /pipes, pumps
The bad:
- very demanding on pc (poorly optimised, memory leaks/etc)
- crashes are often, some people cannot get the game to start
- still in development -> patches are not very often, can break things. The Dev is deploying hotfixes though.
- not much to do yet once you unlock all craftables and fly to planets
- small planets
In overall, a recommendation from me.

This game is pretty controversial, and I've been with it from the very early days before it was even available on the Steam platform. Whilst it's true that the developer has pretty much stopped working on the game, with the last update being on the 22nd of November, 2016, after a loooong time with absolutely nothing changed, I would disagree that the development has stopped because he "took the money and ran" or is "a coward" as some other reviewer has said.
Overall, it's a nice premise. A little bit obscured because of the sheer amount of very-similar games that had a lot more advertisement behind them, but the game has a certain charm to it. Developed by one man, who ultimately stopped development because he has other priorities in life. This game is a plethora of randomly grabbed royalty-free assets (Which I can excuse because it's developed by one guy who, as far as I can tell, doesn't have any art experience) on top of a clever idea. The programming is pretty solid, though lack-luster. The modability of the game is great and it's very easy to take almost every aspect of the game and edit it using Lua scripts and other easily editable files. I'd love to somehow get a hold of the source code of the game and see what it's written in, and continue its development as a hobby project.
Whilst I'm giving this a positive review, there is very little to actually do in the game itself -- But I feel the developer deserves some support. There's a lot of negativity in the reviews here and some of them are pretty harsh and said with no investigations or evidence. Really, it's not about the money for this guy -- He didn't get much to begin with, and the sales for the game never improved. It's more about "He worked on one thing then went on to do other things in life", which is something absolutely anyone who has ever started any project in life will do at least once. This developer was fortunate enough to get his game all the way to Steam, through the OG days of Greenlight when votes weren't rigged. I'd say, for a small scale project he just wanted to work on because he had a good idea, that he got pretty successful for a man with no team and no financial backing.

Unfortunately, as wonderful as this game is, I just have to be honest anyways. Do I play it? Yes, I do, but would I want other people to play it?... Not so much.
First off, the loading times. Sure, that's to be expected in a game like this, but if you have one of the best systems on the gaming market and it takes you 45 minutes to load a game because you added a few extra asteroids, it gets kind of rediculous. If you're like me, and decided to watch Game Grumps while waiting for it to load and finally get in after lord knows how longs, only to discover that the game can't even handle it and you can't move at all, no matter how long you wait, once again, it gets kind of rediculous.
There's no updates... Like, none. at.... all.... It had one update since I bought it 4-6 months ago, and since then it's been dead. Unfortunately, this is undoubtedly a dead game, unless they decide to pivk it up again. The idea is wonderful, SOOOOO much potential is just waiting there, to build upon the system they created. Yet they're too lazy to even considider the community. If you want this game anyways, feel free to grab it, but don't use the generator. Just use the presets, trust me, even when turning the preloading of resources off, it'll still take five hours to load up a world with two standard planets, five random planets, and eight asteroids...
The verdict? About 2/5, that's all I can give it, and until it's proven otherwise by the creators, it's a dead game.
EDIT:
The developer has told us that he hasn't been able to update Masterspace because he's recovering from illness. Given the extensive timeframe, I can only assume it wasn't your average cold or flu. The point being, when this game begins getting updated again, I'll make sure to change the review. Good luck Masterspace developer, and I say this because it's one guy working on an entire game. Give him some love guys ^.^
Edit 2:
This guy has come back and successfully updated the game and made some dramatic changes. This game is now worth the play, and I recommend to people who are especially fond of Starmade. Seeing as there is only one person making this entire game, I have to put into prospect the difficulty of sating the hungry community. This game WILL be successful, but only if it is constantly updated and people are willing to give it a shot. This is to you, developer. Update this game often, and pay atention to what the community wants. If you do this, I gurantee you'll be even more successful than you are now. Good work buddy :)

so far i've built a little house, built a lot of the workbench's and believe i am on my way to leaving this planet! I would say this game is very promising. work on the UI a bit and some of the annoying bugs and it'll be good! Note if you use Nvidia optimus you will have to manually set it to use the discrete graphics card(many steam games have this issue). This is a taxing game, especially on the ram as every planet is loaded into the memory. I have a 3rd gen i-5, 660m, and 8 gb's of ram and managed to max the base settings, however when starting a new game my ram limited the amount of spherical planets I could have. Still built 10 planar planets of ranging sizes and manage to maintain 35 fps. The crafting is fairly simple and intuitive, and the default controls work pretty well. I have experienced a few freezes, one total lockup. overall though as long as you can deal with the occasional freeze(i've read people have lost saves), I'd recommend this game. One thing besides optimization I would recommend is to polish the UI!

I'm not going to tell you that this game is in any way complete or professional. I won't say it's not bugged out with many design flaws and a tutorial that always bugs out before you can complete it, leaving you to figure things out on your own.
But I'm also not going to say that it's a game that anyone could only enjoy because it's-so-bad-it's-good. I bugged out in the tutorial and then joined some friends on a planar world with almost no idea what to do. Between us, we figured out the culture points system, obtained uranium for a quality pickaxe despite the fact that uranium drops are bugged and you can ONLY mine it with a quality pick or better.
I think we beat the bugs.
It's unnecessarily difficult due to bad design, but not impossible to play and enjoy, like we did.
Just don't have too high standards or expectations.........
Aaaaaaand it's 6 hours later and i'm bored of it....

This game caught my eye after learning of Empyrion Galactic survival. They seem like they are realitivly similar but this one is smaller scale from what ive seen so far.
Id recommened this game simply because of its style. Sandbox space games are a thing that will surly pop up a lot more.
This one in particular has a bit of a rough start up if you dont choose the right perk at the start. For example, dont put your first five points into a plasma cannon. You wont get anywhere.
This game is pretty fun with friends. A good time killer for solo play. The ship and building limits cause some interesting designs.
This game has its strong points and weak points like any other. Id say some strong points would be voxle terriforming, multiplanets, a fair crafting/perk system that requires a bit of reading to use correctly, and the visuals arent half bad. Just not the best. Some weak points would be FLOATING TREES (dont mine them, it looks bad), really bare to the bones basic AI that can get a tad annoying when they get in your way randomly, weird gravity on spherical planets that has potential of causing headaches, and audio... I personally cannot play this game with audio.
Overall, id say this is a game to try with some friends.

So...mixed bag.
Masterspace is much like Space Engineers, minus the overly-complicated retardation and lack of anything to do. You start on a planet and work your way up to ships. There's a skill tree, several interrelated build lines, and all of that.
The game is interesting, there's some workshop mods already out there, and it looks good graphically.
Problem: BUGS. Showstopping CTD bugs. I don't mind supporting games in alpha, but this is ... well, I ran the tutorial and it kicked me off the planet into deep space with no way to get back. Stuck in the ground several times, random crashes.
I recommend it but with caveats.
