Which one do you prefer and why? If possible be specific, say the Pros and Cons, so that topic can help some people to make their decisions.
Well, I've been using Multimedia Fusion (The Games Factory, Kilk n' Play) for some years, I still a amateur in that because that I dont use it frequently, its very user friendly and almost anyone can do things on it easily with some practice. The standar engine that come with him is very simply, so its best if you do your own.
As I have seem some people saying, GameMaker looks much more powerful than MF, but with a price that its most difficult to learn, you need more time to undestand it. I cant say much more because all the times that I touched that program in the past, I only spent some minutes and closed it, but I plan to try again.
