creature stage is the best. and hardest. you try to collect all the parts you can, and earn some DNA between your eggs. there was more interaction wit characters here then space stage has
there is actually a point to using both attacking and allying, different creatures for different needs.
once you get to tribal or civ, you can rush through with all allying, or all conquering. neither one really mattering to how you climb the accomplishment ladder.
once you build your creature, and get up to civ, your creatures stats/parts are pointless. and its like all that time was wasted :(
and i don't really get the point in the vehicle parts having stats. theres only 3 things that matter weapon/speed/health.
and you can easily max out all three on any vehicle first time you build it. because they give you a huge load of money that you dont even need.
there should have been unlocking and finding parts for vehicles, just as creature had.
Im not happy that at civ/space, you no longer have your little guy. they just generic "people" avatars running around the cities for looks. You cant select them or do anything with them, cant even zoom in close enough anymore to see them nicely. things just simplify to much at later game
