Recent verbatim reviews from Steam — separate from playze.io community reviews below.
Gaia Maker is a great free game to spend time. At first I couldn't understand but after I got the hang of it watching and growing civilizations and planets was so cool. Overall, I hope this game continues to get updates and new features. One thing to note: I feel like the game is too easy (especially if you know what everything does) when you speed it up. I wish it was a little bit more balanced on the difficult side. The game also doesn't require any high end device to run, as my HP Laptop (far from any good gaming PC) can run it easily with 150+ fps.3 found this helpful
Its cute, its simple in its sub-game scope. It applies a lot of the ecology flows that makes ecology sims so fun to play and watch. Civilization history does feel a bit simple, and the water flow and tables systems are unclear, like not telling the user how oceans seem to flood at negative heights... which is weird if i knew i could(not) add more water to the planet to raise the water table. And that comes from realizing there are ways to rise and lower land at the cost of heavy atmospheric unbalance with albedo increasing. So in a sense to change the land the weather systems have to tank or be done very slowly (forgetful) to not freeze the planet. I think these systems just needs more history charts to know when planetary limits for water and its behaviors are reached, or history of civs that came and gone over time in respect to balanced ecologies, and generally get a sense of the appeal being an eternal hyper-technical being that can terraform this planet for eons well noting it all down.
basically a SimEarth remake, although it feels more like the TurboGrafx version of it, which makes sense since the developer is Japanese. it is pretty good but don't expect much changes from SimEarth, it's very similar
A really cool game, maybe a bit simple but still, incredible, no lag problem and the only "bug" I found was when I clearly was just screxing around trying to spawn a volcano on each tile of the planet and well... yeah but still, good game if you have a couple of hours of boredom (also disrespect to the one guy that did'nt reccomand just because he think some other game is better boo him everyone)
my planet was too efficient and caused the fox civilization to flood my planet, so i set plagues and fires to limit their numbers to give other animals a chance, and caused a total ice age making everyone extinct. LOL. entertaining for a run or two, even if this style of game isn't your usual.
Fun game, reminds me of Sim Earth.
