Of course. Do it as a hobby. However, doing it as a hobby and as a daily job are two VERY different things.
If you want to create games, you don`t have to recreate whole engine from scratch. Just use some well-known free alternative (Ogre/...) and concentrate your efforts on gameplay. It`s gonna take at least one year to accomplish anything partially meaningful, but if you really want it, it shouldn`t be an issue.
eheheh....Thanks WTF4096, 1 year is really not a issue.
