What don't I like about steam? I don't like how the steam client constantly updates itself and forces me to update before I can do anything. I don't like how I need to sign in/start Steam in order to play the game I purchased. I don't like how my games force updates on themselves, preventing me from playing until it downloads whatever huge patch awaits (even if I intend to only play single player and my mods were only compatible with the previous version). I don't like how for many games it constantly pops up the steam overlay to tell me about a CD key I never need to enter. I don't like the pop-up ads that come up every single time I turn steam on, or restart steam. I don't like the little achievement messages that pull me out of my game and draw attention to themselves.
Yes, I know that these also apply to Origin or UPlay or any other always-on digital platforms. Yes, I know some of this stuff goes away if you specify it in the settings for each game profile. That's not the point. The point is that sometimes I would prefer to just get the game, install it, and start playing. No pop ups, no auto-updates unless I specify otherwise, no auto-syncing, no forcing my computer to run steam and be connected to the internet.
Remember how much complaining there was about DRM when it first came to be? Steam is DRM. Every time you try to play the game, and it says you cannot play unless Steam is running, it's DRM. It's an extra step, an extra login if you switch computers.
Are there benefits to Steam? Of course! Download any game you own whenever you need, no searching around for a patcher, easy mod support, community features like friends and chat, achievements, save game sync, etc. But that comes with a price, a price that is very evident when you have flaky internet.
And god forbid you ever get your account hacked or banned. For the convenience of putting all your eggs in one basket, thousands of hours of gaming, thousands of dollars spent, all in one place for the stuff you paid for...one day Valve can decide that you no longer get access to any of that. And there's nothing you can do. You pay for the privilege of using their service...Valve owns those game licenses and lets you play them.
Of course I use steam, I've used it since 2003. I don't go out of my way to avoid it. But just because the original fears of "what happens to my games if Valve goes under" have gone away doesn't mean I'm not aware of what I'm sacrificing for convenience. Don't discount the negative opinions of Steam just because it's "convenient and cheap", there are legitimate reasons not to put absolute faith in one company. Hell, even EA used to be looked on as a leading company in the industry, a shining beacon of what could happen if artists were given the influx of cash necessary to make their creative dreams into reality. Times change, companies change. Just ask Maxis, and Bioware, and Westwood, and Mythic, and so many others what happened after they put their blind faith into one company.
