I don't like the 'idea' of steam, but lately I've begun to use it daily.
At least for me, it seems the most reliable Digital Download distrubitor to date. After the shift in Impulse ownership, my old laptop had troubles reaching the Impulse servers ... and now I am currently locked out of my Impulse account due to a new security initiative.
So yea, as far as this sad, sad state of affairs when it comes to gaming, Steam is the better of the various poisons (better, I may add, by leaps and bounds).
So certainly I could say that I support steam, at least as much as I have to, but I am not necessarily a 'fan' of steam. I like steam about as much as I like the CocaCola company, or Hersheys, Walmart or Bestbuy. I don't particularly like them, but they are relatively good at what they do, and its better than living in Industrial Revolution Britain where the peasants only got potatoes to eat (due to the nature of British law, economic decisions, etc, the Potato replaced the normal variety of food the british lower class were able to eat, thus causing health problems and disgruntled peasants).
That being said, 10 years from now when I dust off one of my old computers from storage .... will I be playing my steam games? probably not. But I WILL be playing those games that don't require such services ... such as my Rome Total War, and my Medieval 2 Total War. (both bought with CD keys only, no steam or steamworks required).
This new fad of 'lets all play the game at the same time and then stop doing so once we get tired of it and abandon the servers' isn't exactly for me ... I like to play a game once every 3-5 years or so. Just depends on the game and the circumstance ... but yea. Sometimes I don't finish a game until I've played it off and on for 10 years, just because of some nuance, level, or I just got bored with it a few levels in (the first time).
Compare this with certain games where I destroy the campaign within 72 hours of opening the box (Bioshock, Assassin's Creed, Hunter:The Reckoning, Hunter:The Reedemer) but the point remains ... my playstyle across the passage of time is highly irregular, and therefore I don't like being dependent on the public at large (companies, servers, etc) to determine whether I can play my single player game or not. I play games (sometimes) to escape reality, not to simply add a layer to my interaction with reality.
For now I will buy and play a few games in the steam format, but I doubt that these are the games I will be playing in 5, 10, or 15 years hence. Games that I can simply dust off, plug in, and play ... (albeit perhaps with adaptors or emulators) those are the games that I'll keep on playing into the Golden years.
