We pretty much all have school. I have it and I've found time to learn TorqueScript, create the Team Deathmatch mod, a CTF mode, learn Blender and make flags, and then start and have nearly finished a talking, attacking and other bots mod.
You don't have time to learn one modeller and copy a few things from a game? Besides, if it's availiable somewhere for RTB it's very, very easy to port.
