ff7. I spent most of the end of the first disc going 'wtp? this is weeeeeeird.' and then someone told me the second disc was weirder so it ruined the surprise:P

5, 8, and 10 don't seem as weird to me. . . I guess it's from knowing their stories too well (ten especially doesn't make sense until you replay it a time or two)

vegnagun in x-2 was creepy for a large portion of the game though.
