I guess I'll clarify my vote if it's not obvious.

I'm voting for 2 for two reason. 1) I like the idea of consistency and professionalism within the game. 2) No matter what mix we do of sprites if we go that route, there will ALWAYS be people who won't like some of our sprite choices. Whether it's "hey why did you use the D/P Growlithe?" or "hey, you guys used HG/SS Jolteon! That sprite sucks!" we will never make everyone happy. So we may as well be uniform since not everyone will approve of our decisions anyway.
