Sadly, there isn't really one that is that great. Spore was supposed to be...but...we all know that one.
Spore didn't even allow that much customization. Everything was pre-created for you, except the body of the creature...it been cooler to allow pre-created parts, but allow you to create your own mouth and stuff. As it was, placing a mouth on a Spore creature looked ugly as hell. That is just one example of pre-created parts looking horrid in Spore. Best part of Spore? Cell and space...
Spore was really limited too. Why couldn't I be something really tiny, like an insect and live as an insect colony? Like sim ant? They could have just put sim ant in the game and more modern. NO! I had to be a boring land creature.
A real evolution game isn't about mammals...that isn't realistic at all. What about insects? They evolved WAY better than most land mammals ever have. Heck, ants (as a colony) are smarter than most modern day humans...and not nearly as lazy. Work harder than any freeloaders who want free free free.
What I want in an evolution game?
Full customization. No stupid looking pre-created ugly ass mouth (or eye or anything else) parts that don't fit and look completely out of place. Able to be a sea creature, land creature or an insect. I don't even care about space. But make the world huge, gigantic, titan size, so have a ton to explore. But not barren and empty (even a desert has a lot of life). Don't bother with space, just focus on the planet...as a sea creature, you get to swim in a 3d sea. But later on, gotta watch out for civilizations who hunt (fish) for you or a number of hazards. As a land mammal, you have the potential (but rarely) to evolve intelligence...and it plays out like a real civilization would. So it turns to a total war style game almost, but a huge city builder with politics and wars and all that. But if your civilization turns lazy, it collapses on itself...or apocalyptic wars...
Or play an insect, in a modern day sim ant setting...whether its an ant or something else...every blade of grass will look giant to you...but watch out for civilizations that use pesticides and want to kill you! Or being stepped on...or ran over...
Or a deer (for example, it probably be something else)...or any number of things
maybe later, when ready, add space...like a huge expansion...but later when everything else is finished
Now THAT would be a game I'd kickstart.
