In my previous article I talked about how to create an RPG all by yourself. In case I wasn’t clear enough: the conclusion is that you shouldn’t attempt to do everything by yourself, unless you seriously know what you’re doing.
It’s possible to speed things up by taking advantage of what other people already created. RPG’s seem to be very popular for game development projects, and a lot of people have made their own frameworks or even art available. So why not see if one of them fits your needs?
