Guys, please stop calling it parcour cause it's parkour, nothing horrible, but it just kills me... About flips, they really have nothing to do with parkour (yamakasi is just a name of first parkour team, it isn't an other kind of sport), if you thinking about adding flips (which are useless in shooter game in my opinion, same as shooting cause to move through obstacles and shoot someone isn't realistic, I just don't like that idea, but I think it'll be ok if you game will be arcade) that will be freerun, but not parkour (yes, they are different). About BRINK, I really hate it, cause I don't like movement at all, I don't like idea at all either... The best parkour game I've ever played is Mirrors Edge. Great balance between moving and shooting in my opinion. If you have some questions about parkour (or freerun as well) send me PM, I'll be happy to help.
