Atlantico: Steam just rubs me the wrong way. The first time I saw someone use it, I just noticed it monitored how much you played each game. Overtly, it wasn't even hiding that it was spying on you.
Also, I preferred boxed games, I like the boxes, the cover art and the nice feel of a physical copy that I can put in my shelf. Mmmm nice! And then I bought FO:NV and it installed Steam.
That also rubbed me the wrong way. I didn't ask for Steam, I had bought a physical copy, and yet here's Steam on my PC.
Then I actually bought/leased/rented a game from Steam and had issues with it, I couldn't run it despite meeting the minimum stated requirements. Tried to ask Steam support. Well they took a week and two emails to tell me, too bad so sad, google for help or something because we're not going to lift a finger. And forget about a refund, even though I had never been able to launch the game at all, as their spyware of a client could have told them.
Then there's the DRM aspect, the shovelware aspect and the general bloat around and in the Steam client. If Steam ever served a purpose, it doesn't any more, so I don't feel badly when I say: fuck Steam.
GoG and other hosting sites "monitor" time spent "ingame" and your purchase preference... (dunn dun Dunnn) Just like Steam.
What I don't like about Steam is the popular games get the Attention while older games are dropped and no support is given at all, their like "oh you still play Fable? (snicker) umm you could try Some Randome useless action to get it to work or you could just Buy This shiny new Bethesda game for 70$ right now!!! come on you know you wanna buy it!!!" that and their "discovery queue is total Bulls..... No I don't want to buy that japanaese anime porn game.... why did it pop up in my Queue 70 times?
