I have a copy of Worms 3D (legal, cost me £40!!!) here, which I would really like to play on my Mac. As I have done with all the classic games I OWN (Quake 1 & 2), is there a way I can just download the game engine as an APP to replace the EXE? I really don't want to have to buy it AGAIN. Not really worth £80 is it?
