Damn, since I can't modify the post for the second time, I won't have any remorse doubleposting

Especially that the lack of this option just ate a chunk of what i've written :/
Baldur's Gate 2: Muscular female half-orcs on the inventory screen. They look like regular humans in the game though.
NWN 1:
muscular, playable, female, half, orcs. Ugly heads (boar-like faces) but there are mods out there which replace the regular heads with beautiful human ones.
Also, I should have a mod somewhere on my hard-drive which replaces some in-game model with a REALLY muscular girl. Her body texture is unfinished (looked quite good to me, though) and her head was based on the divine Anja Langer.
NWN 2:
again: muscular female half-orcs with ugly heads. I've got a model on my hard drive converted from regular human female, which replaces one of the ugly heads. Her eyes go weird from time to time though, due to the differences in the skeleton shape.
Last but not least: if you want to have your favourite arcade game muscle girls from fighting games all in one place, try googling for MUGEN and searching for the characters. I know there's Angela Belti, Rila, lot's of different Chun-Lis and Cammys, Storm, Psylocke, probably more.
