It really depends on the vibe of the game and the character.
1, 4, and 12 are goofy, and wouldn't fit a serious game, but would suit a fun and wacky game very well. 9 would work for serious.
Most of them look modern (except perhaps for 1), so if it hasd to feel authentic, it'd have to be 1.
5 and 6 have the most appeal to me, but that might just be because I'm a witcher fan ;)
I can't take the dude in 11 seriously :P
