I once dreamt about TimeSplitters: Future Perfect. I entered the "MapMaker" mode, which is a very flexible editor, but not extremely (i.e. no diagnal surfaces, allies, bumpy terrain, etc.) and I dreamt I found a way to do all that by inputing a code somewhere (in a non-existant text box in the MapMaker) that unlocks such tiles. When I woke I was pissed off.
