We've all seen the amazing abilities of Dark Physics, but lets face it, as of yet there really hasn't been any innovative ideas that harness the physics engine without giving the impression of "I stuck this in here because it looked cool". What I think is needed, is true implementation of physics, where the very game depends on it in some new and fresh way. So, I purpose we all share our ideas!
My Idea: Magical Anti Gravity Wand
Can be used in: Action or puzzle oriented games.
What it does: Moves objects in a gravity defying way, which could be implemented to move certain crates out of the way, or stack them up so you can hop from one to another to get to a higher area. Also could be a form of attack, such as lifting up nearby beams and hurling them at enemies. Could be a bit to powerful, so one could limit the power with a "Wand Power - O - Meter" type system.
Well, there's my "novel" Idea. Yours?
