this video (http://youtu.be/_xFbRecjKQA) gave me an idea.....
I was thinking a tall semi industrial kinda level, with walkways/footbridges that go back and forth across the way, maybe some are just a box.... but they can't be jumped to, the way to get around the different levels/layers/bridges is to walk off the end of a bridge- a bit like the mada tamaha level, except each bridges ends take you somewhere else, and maybe where it takes you depends on which way you got to that bridge, with one of the bridges or boxes only being reached by a certain combination. Possibly a quest location/instance that can be revisted (at anytime after having been quested to there....)
would something like that be possible/plausible?anywho, hope that this comes around, a street that trippy would be great fun!
