The one you create that is! http://www.onrpg.com/ I bet making it would be a bitch, but think of the possibilities! All I need to learn is C++ How long would it take to make a game using C++, btw?
i'd say from 1 hour to 100+... always depens on what you want, C++ or not. you want a pong-llike or the next everquest? (don't care about the genre, just care about the complexity between the two.
You can make 3d games with this?? Well, I don't want 3d stuff, but I'm prolly not gonna screw with this stuff anyway.
