How can I make money from a video game I made?

Alright, so I'm getting into 3D modeling, and found that I'm actually quite good at it. I've also been told that I'm really great at coming up with ideas for games. I don't want to get ahead of myself, but let's say I got a couple of my friends who know programming (I know a little myself) and we made a game, an RPG for example. I'm not saying I want to make the game so awesome it could compete with the top dogs you see at GameStop or anything, I'm leaning towards Runescape-like type of game except not online. So if I actually made a game like that (I got the software needed btw, ex: Maya 2011, C++ compiler, Java Compiler, Photoshop, Zbrush etc.) how could I make some minor profit out of it (I mostly want to do this for fun and to gain some experience, but I would also like the game to pay for the time)?
