I downloaded steam, in both osx and xp, and I dont understand why everyone talks about it, loves it, or uses it. Is there something im missing? I mean, you can buy digital copies of games, but I buy hard copies...so I dont need that function. You can put games into your steam library, but why?...you can just put them in a desktop folder. Please help me out. Am I missing some crucial aspect of steam that is holding me back from gaming bliss?
