I only purchased physical copies of game for the PC. Then I tried a few services and found them to be lackluster in many ways. I found Steam and it's not perfect but I believe it's the best place to purchase your digital games and create a library of games you want to collect and play them wherever, whenever you want.

I hardly purchase physical copies anymore, why would I want t to have games at 3-4 different services? I don't, that's why I decided to make Steam my home for Digital downloads of games. I only purchase Collectors Editions that I really want physically anymore.

I didn't enjoy Half Life 2 (it was ok imo) but I do enjoy Steam. :)
