TBH, I don't think this mod took much work at all. Sure, I don't know how hard it is to re-do the collision engine or whatever they had to do, but if you look at the TDK, which was released 1 1/2 years ago, it really hasn't changed that much :\ From the looks of it, this is a 1 year mod that took 5 years to make. Still a great idea and they did it rather well, but I'd hate to wait another 5 years just for a patch <_<
