I never fully understood why people would re-buy games they already have just so they can put them on steam. Isn't it cheaper to just make backup copies of their game disc? I guess I'm just a bit of a scrooge and go out of my way to save $5-10 bucks on a game.At $5 to $10 a lot of people will re-buy games they already have, to put them on steam. I know I do.
