I know someone who's making a game with Clickteam Fusion and considers it almost a form of betrayal to go with GameMaker. :-p So when I brought up GameMaker, I was thinking of mentioning Clickteam Fusion as well, but the usual cost is $99. I don't really know enough about it to know that it's worth that price tag. Now that it's on sale, I guess I'll be picking it up just in case I want to use it sometime, just like the other one.
