Free-running isn't the same thing as parkour. Parkour is getting from one place to another in the fastest way possible, free-running is doing it in the coolest way possible.
Now that i got that out of my system, i haven't played many games where characters do things like this, so i will just choose Ezio from the last 2 AC games because he seems to do it well.
There's only been one PERFECT free-runner, the one guy who's made such a mastery of it, mistakes are something he picks out of his toe jam each morning. I'm of course talking about the time-control master himself, The Original Prince of Persia!
Altair and Ezio are easily the best free-runners they're the only people i know who climb up 100 yard walls using 1 inch out hanging boards and poles. and jump off a fifty foot building onto another and and make it.

I would say Nathan Drake, maybe he doesn't have all the moves and skills, but his adventures are just epic in every way. Maybe that's why UC3 got 10/10 by every gamesite..
