HereForTheBeer: Some 120 posts into the thread so I'm fairly certain all this has been mentioned prior to my own ramblings...
First of all, do what you like. If you like Steam over gOg, that's great. If you like certain aspects of both, also great.
Myself? I freely admit to being polarized, and this position was strengthened after my refusal to acquiesce to a change in Steam's EULA meant that I was locked out of a game that was purchased at a brick-and-mortar retail establishment and not from Steam; the game came with Steam integration as a requirement for installation and use, and the change in EULA came
after I had been enjoying the game for months. After they pulled that stunt I finally got the title working outside of Steam, thanks to info provided by the developer and users on its forum. This incident with one title was enough to wave a giant warning flag in my direction: continue to agree to whatever future requirements we impose, or kiss goodbye to all of your Steam-integrated titles.
Having spent well over $20,000 on this hobby over the past ~25 years between hardware and software, I think it's reasonable to expect that the devs / pubs show me a bit of trust when it comes to buying their titles. One service does this, and one service does not. I buy nearly exclusively from the one that does, and I buy
NOTHING from the one that does not.
Do I miss out on a ton of games, especially new and former AAA titles? Sure. On the other hand, my giant backlog essentially makes this a non-issue: it'll be a long, long time before I run out of titles to play, even with my self-imposed purchase restrictions.
For me, it's as simple as that. I've sunk too much into your industry over the years for you to continually to treat me like a thief. That's piss-poor customer service and a lack of respect - "We don't trust you, but please continue to throw money at us!" - and I won't support that, especially since PC gaming is a completely optional pastime.
