So I decided to take the level back into Unreal, to make it a playable game again. I was interested in seeing firstly if it was playable, but also if it could be played normally like before or if it had transcended into something else a different kind of game.
Getting the positions into 3D and essentially "re-creating the level" based upon only the most popular parts of the map was fabulous (or at least I thought it was).
