TerraTech

Not a game that requires much thought; mostly turns into which 'tech' has the most guns but still a very chill and fun experience if you enjoy building.

A fun sandbox game where you build war machines, collect resources and make factories. The thing I like to do most is building the biggest vehicle I can, and then put all my weapons on it to make a behemoth of destruction strong enough to win WW3 on its own.

Yeah its pretty fun. but there's only one playstyle. i wish there was more options regarding being able to turn down the obnoxious enemy aggro and spawns, i tried to do a harvesting peaceful run, but no, enemies every 10 meters, and the ONLY way to deal with them is blow them up, so why have the entire crafting harvesting aspect if you harvesting craft needs to be shielded and armed to the teeth just to stand a chance of getting back to base with enough resources to cover what you lost getting them.

TLDR, add settings to customise enemy spawning and AI

OVERALL FUN. Kill the hostiles, scavage the remains, make yourself bigger, faster, stronger and better. dont worry, they die slowly for your satisfaction. no blood, no gore. just tech on tech slaughterfests. the evolution from small and scared to big bad boss guy is slow and annoying, but very much worth it...and so very satisfying

TerraTech!
This is a cute little game made for people who really like building LEGO. Since that's basically how it works. You snap pieces together into whatever you can think of. Like hovering tanks with jets. Or goofy-looking cars with auto-targeting missiles. Or a massive tank-treaded behemoth with an ungodly amount of firepower, casting a mile-long shadow over once-peaceful grassy plains.
You start as a scrawny cart with maybe one or two guns, beating up enemy Techs your size and hastily taking their lunch money.
As you destroy more rival Techs, you'll collect the blocks they drop, using them to augment yourself into a perfect killing machine. Missions and building factories will also net you some cool stuff.
Alternatively you can play in creative mode/the R&D Labs DLC, which are both fun experiences that give you the chance to build anything you want.
The game has modding support, ranging from skins to brand-new blocks, weapons, and even more game-changing stuff! (Note: for some mods, you'll need to install an external modloader, but it's a very quick process.)
And, the best part?
From today to February 18th, it's only $4.99/$6.39 with the R&D labs DLC, on sale!
I would definitely recommend buying TerraTech if you or a relative love building games/LEGO. Since there's online co-op, too!

Starts out slow, but things start to get good after you get a good vehicle design.

A wonderful Sandbox game that sets up a lot for its successor to live up to. Survival is fun and there's a ton to do, and the possibilities for what can be created are immense, especially in Creative Mode. The environments are somewhat bland and repetitive, and late game Survival doesn't leave a lot to do once you complete everything. Mods make the game much better, but can really break your game if you download ones that conflict with each other.
