The Little Lifeform That Could

This game owes a lot to Spore, but where Spore disappointed me by being shallow versions of a bunch of genres strung together, this is much more cohesive and consequently, I actually prefer it to spore. It has a similar sense of humor, though it is written with a very modern informal tone that might be hit and miss for people. Speaking only for myself, however, it was right up my alley and I very much recommend it.
