When I was about 12-13, I tried to make an RPG with RPGmaker at a friend's place. ....it sucked. It really did.
When I went to college, I downloaded RPGMaker myself, and tried making an RPG. IT was cliched as all hell, and the maps were a little lacking in detail, but it was alright. Didn't make all that much of it, though. Only one continent/chapter, and about half of another one.
And then I got involved in an RPG project a friend was making. THIS one...We have most of the story planned out, about 1/5 of the game done, and it's looking pretty good. ...But considering how much work we have, neither of us has worked on it for a while. :s We DO want to finish it, and maybe some day make it into a REAL RPG. And then share it with the world. ...It's not likely to happen, but we can dream, eh?
