Games - randomperson

I from the United kingdom and am in year 11 of school. I have been interested in computers for about 10 years now. I started modding about 2 years ago when I had finished red alert 2 and was wondering if there was any way of changing the game. I found this site that that propelled me into doing some modelling. I mainly model for command and conquer but I am happy to try any game.
