Confusing and Boring
I thought that playing God and creating a world would be fun. Instead, it's utterly pointless and boring.
None of the game dynamics are explained. Adding CO2 or nitrogen into the atmosphere had random effects. I was just tinkering around with various stuff for hours and didn't understand anything.
Most importantly, this game was not entertaining! This game felt more like a simulation for school. The planet thrives and changes, but nothing interesting ever happens. All sim games don't have explicit goals, but this one didn't have a sense of accomplishment! There needs to be wars, exploration, worshiping or something to make me want to play it! After awhile, I just didn't care about what was happening.
