I'm with kread on this one. Even though I have learned quite a bit of Ruby while i've been here, i've been branching of into C, HTML, JS, CSS, and a few other languages so I might have some understanding when I hit college. You gotta remember though, you not only have 3 axes, but physics as well. It's wise to wait awhile. I would recommend though, if you want to get a feel for 3D rpg making, to try the Playstation rpgmakers.
