I want a game with a metagame of breeding/evolution. Cross and mutate your pets to see how they face obstacles and overcome challenges. Watch them get born and die. Watch the shape of the family tree: will it split into specialized subtrees? Will you accidentally lose some genetic diversity you need to progress? Massive Chalice was a great example, where the pets metagame was about managing a dynasty of fighters, and at the lowest level it was a tactical fighter. The genetics system was relatively simple, and I want to see what it's like when it's developed further.
