There's been quite a few over my very nerdish years :D Lesse~
KOS-MOS from Xenosaga, I don't know what it is, maybe a combination of the fact that she's an android, completely powerful @_@ and like... super sexy~
Another I thought was pretty hot was Quistis!!! From FF8, I dunno, she seemed so much more humanized then any other FF character before :P Gotta love the business/teacher type of woman :D
Ayane from DOA series was always a looker ;)
Blood Rayne ^_^
Absolutely with Nariko!
and I rently thought Lady from DMC4 was pretty stunning :D
Then theres about a billion classics from numerous fighting games :D All in all, so many!
But MASSIVE kudo's to Parasite eve ^_^ That chicka was hot!
From 0 to KICKASS in .stupid seconds.
