Might as well jump.
Despite what the title may lead you to believe, the Free Running game actually has more in common with Parkour. "Aren't they the same thing?" you cry, understandably confused. "No", I reply. "No, no, no."
I once thought as you did, that there was only one urban sport involving running around and jumping off rooftops, and that it had two interchangeable names - a flouncy French one, and a more prosaic English version. Then I did a little Wikiresearch for this review and discovered that Free Running and Parkour are now totally different things. David Belle, who appeared as the runny-jumpy guy in Luc Besson's District 13, represents Parkour. This involves getting from one point to another in the most efficient way possible. Sebastien Foucan, who appeared as the runny-jumpy guy in Casino Royale, represents Free Running. This involves getting from one point to another in the most stylish way possible.
See? Totally different. Don't laugh. It's a serious distinction. Google it. People get into fights over this stuff. Tsk.
