DCUO currently has a "movement system" like this, one of 3 actually. Flying, super speed, and acrobatic (wall scaling, double jump, grapples, etc) would be nice to see in a mod eventually. Maybe I'll make that a focus after CK comes out. Only problem I see would be there aren't many buildings to scale outside cities. Walls into and out of cities would be unscalable or else getting stuck off the map etcetc. And in some dungeons they require you to lower bridges in order to progress, such as Geirmund's Hall in Gauldurs amulet fragment quest. The current way around it I suppose would be to type: player.setgs fjumpheightmin ###
