This is exactly the reason Why i like to buy a game, so you have a disk, a cd key, and something to show for your money.
The only games i own on steam is games that are only available on it.
Counter-strike..
Half life's..
Huge list aint it lol
I was of this view but now more and more games these days insist you have steam in order to play them even if you bought the disc from a shop like shogun 2 and metro 2033 etc.
