In Killzone 2, you play a midget on a rampage.
Okay, you might not technically be a midget, but you are pretty short. It took a while before I wasn't frequently thinking I'd somehow toggled crouch. Your eye level seems to line up with your squadmates' nipples. The other guys are good about not teasing you. They're a talkative bunch, always cussing and expositioning and saying things like "Get up on that tank and mow down those Higs with that em-gee!", but they don't ever bring up your height.
I don't know if being Napoleon-esque is unique to the special review build Sony sent games writers about a month ago. Maybe among the final touches is the main character's growth spurt. But all I've got to go on is what I've been given. Sony's even okay with reviews coming out nearly a month before the game's February 27 release, which means I can talk about much more than their sensitivity to midgets by making a game with a midget lead character.
