Anno 2205

Solid Building Game
Anno 2205 is one of the weakest parts of the series. I don't think it can compete with the others. The principle of anno is very simplified here. There are many features in this game, but after 10 hours you have seen and played through all of them. It doesn't have the potential of a 100 hour endless game. Nevertheless, I would recommend this game, but only in sale.
I would like to add that ubisoft connect is the shabbiest launcher in the world. Ubisoft if you're not even willing to update and improve this launcher then get rid of this junk. I honestly have to confirm 6 times before opening the launcher that it opens, then I have to log in every time, it can't remember my data. I must have the launcher opened at all times so that my rewards are available ingame. There hasn't been any progress for years!

Keep coming back to this one. Its worth tracking down the big update mod for it. Google
Anno-2205-Revolutions-Mod-English if you want to give this another shot.

The game is great. I had a problem starting it. If you already have a Ubi account, you must close it first, then start the game and log in again to pair the accounts

Hardcore Anno fans hate this game because it greatly simplifies goods transportation. If you're coming from Anno 1800: There is no trade routes between individual islands, only between regions. All trade routes are chartered routes.
It's like an Anno for newcomers / casual city builder players. You'll still lose tons of hours. It's still really fun. Honestly it's 100x less of a headache than Anno 1800. The biggest downsides are you can't play sandbox mode and you can't manually save (you're essentially playing permanently in Ironman mode).
Call me crazy but I really enjoyed the faux-RTS ship combat missions. I dunno. It's something I never knew i needed and something I now want fully fleshed out in a game. Anno city building with proper Dawn of War 2-esque combat missions.

1404 was good
2075 didnt play too much
2205 best Anno game for me - transport system is super easy and clean, no big hassle with figuring out whats wrong with a trade route or anything, just enjoy
1800 is 1404 with fancy graphics..

By far my favourite ANNO and city building game.
+ Good entry point for interested players in this genre
+ Great variety with DLC (super cheap and included in Ultimate Edition) with each land type (mediterranian, arctic, swamps, moon surface, space station) each having different buildings and mechanics for city building, such as space station builds like a ribs on a spine, arctic living buildings need to be close to heat generating industrial buildings otherwise homes are cold, moon settlements require shielding from small meteorite fragments which need a lot energy, swamplands need to go be made habitable little by little, and all of these lands run their cities and economies on different maps at the same time, each having a dozen unique resources that people and industries on other land types need, and you'll need to create a complex logistics and production network so that each land supports the others but also has enough for it's own, and EVERY building is unique, it's not like "ok this is a mine, + a stone icon on top", it's unreasonably stunningly detailed and creative, feeling real.
+ The sci-fi theme is very grounded and feels real, offering the best visual variety across the franchise with stunning maschinery
+ / - User friendly but "maybe not hardcore enough" for some: pathing does not matter. If you produce X amount of something, that goes into your storage instantly, regardless of how difficult it is to reach the factory by trucks. Traffic is for show only. On one hand, this might be off putting for more hardcore city builders, on another it's very welcoming for beginners and logistics comes from intercontinental (interplanetary!) logistics between maps really.
+ / - Once you "finish it" by constructing the nigh infinite energy building, which is the goal of the campaign story, there is not much left to it. You can start over, but it always feels the same. Little replayability in this sense, but I find myself reinstalling this game about once a year and playing it again from 0, instead of throwing cash out on a newer entry, because it's damn good enough that I don't feel it becoming outdated technically or overshadowed by a "better" entry. It's gold.

My brain exploded when I got to the Moon. All Anno games are good.
