lara croft

Zero Suit Samus

I'm not sure who is the top, but Nariko is pretty damn close.
This guy agrees with me, though he may be taking his obsession a bit far:

"Holy moly! Nariko is perhaps the most stunning heroine I've ever seen in a game. Is it possible to fall in love with a virtual creature? She is truly beautiful, and those glimpses of her tush certainly are enjoyable...

I hope I can get over the fact that Nariko is only virtual. She embodies pretty much everything you could want in a woman (just don't tell my wife)."
