There is a Program called Realm Crafter, that lets you make mmorpgs. Its almost like FPS Creator only a little harder. No coding required, but lots of scripting. Bad thing about it is first of all it cost $100(about 73 euros I think). And if you add to much to the game, its gonna lag. Its also hard to understand. And also you gotta find a host for the game server(around $50 a month I believe, I could be wrong). You can just use your computer, but like only 30 people can play and the same time before it really lags a lot, and possibly freezes. And you would have to leave your computer on 24/7.
But if you happen to make a great looking game, and make sure it can have a lot of people on, you can buy an extra peice of software, where you could charge players per month. That would make a lot of money (5 subscribers at $5 a month = $25 a month profit.) but it would have to be REALLY good.
There are a few 2D MMO makers, use google.
Correct me if I'm wrong on anything.
