I've seen some people complaining about too much space (Hong kong) and i wondered what could fill do with the space and make the DX revision experience more exciting. I thought about it and remembered 'Jump Quests' from a free game called Maplestory, you jump onto platforms to get to a certain area (I.E the top). on the way there are obstacles which will knock you of the platforms, it's a very simple idea (maplestory is a 2D plane).
i was thinking that we could do some jumping to get somewhere where there's a reward at the end, kind of like when in DX you start at the mole people and make your way to the airport through sewers Ect. so how about obstacle courses or dungeons/buildings with laser trip wires cameras and mutated animals. sort of like a training ground but we get rewards at the end (and each building has its own side story??)
