Other than Mirror's, AC, and Prince of Persia (which doesn't really have proper parkour)
I quite like parkour, despite not being a traceur myself. (complete nerd, fat and suck at sports.)
Those first two were the only two I could think of.. It's a shame because they're really awesome.
Indeed they are awesome.
Parkour isn't in enough games.
I'd personally like a side scrolling beat em up (but no "lanes" or anything, just straight along) game with a focus on parkour.
