If you had the funding from a major company and total creative freedom, what video game would you get made?

Evolution themed team combat game. Both teams start with a basic set of skills and abilities, claws, teeth, etc. And as you complete objectives (capture the flag, killing an opponent, etc) you get to evolve new traits. Think competitive Spore, with hints of TF2. There could be different maps based off of environments, deserts, oceans, rivers, mountains, with each having their own environmental hazards to contend with.
