Hey MPG,

If you want to make games, but still need to fill in some holes with your c/c++ knowledge, I would suggest checking out the game development tutorials at <a href="http://www.gametutorials.com/>Game Tutorials.com. It'll give you a chance to make some fun stuff and learn c at the same time.
