New video game idea

I've got a great new idea for a video game! The setting will be a great trans-Antarctic war between penguins and kiwis. Having inexplicably crossed the Southern Ocean, the evil kiwis will attempt to take over the icy realm of the penguins and drive them out. Though both are flightless, in the game they will be capable of great acrobatic feats, running up sheer walls of ice and leaping from one rocky crag to another, making flight itself seem unnecessary. Their tremendous fighting skills will be exhibited in a whirlwind of martial-arts moves which, though computer generated, seem uncannily real. And, best of all, defying centuries of macho stereotyping, these avian warriors will all be gay.

I'm going to call it "Ang Lee Birds".
