Well I actually just checked Steam and you can play all 4 OddWorld games.

Cost is £12.99 and Im buying an Alienware laptop in a week or two anyway, so it will run amazing.
I think im going to with Steam as it works out cheaper and easier, just a controller to worry about now. Anyone got any suggestions on controllers that work and I dont have to setup controls everytime I start a game up.
