Help me out?

[Ender]

Alright, so I want to go into video game development.
I'm really good with Maya, and I want to create characters and worlds and weapons and such, doing that. I am however not a very good artist on paper. I'm a senior in High School, and it's kinda late to get into art classes. Any advice? Also, what is the name of the position(s) I want to go in? What should I major in college?

Thank ya much.
