Hello everyone! For the past week, I've been searching for a good game to mod (in particular doom, dark souls, half-life 2 or some kind of 3D platformer). Problem is, having a mac is cutting me off from a lot of good level editors like Doom Builder. Can anyone tell me where I can find a good game with a good level editor for mac?
(I know this may sound kind of stupid, but I'm kind of new to this. So bear with me a bit please.)
