So whats your explanation for why Civ 5 has outsold the entire previous Civ series on Steam?
It does look to me like Steam has created consumers out of pirates. As a former habitual pirate myself and friend of about 10 similar, we all suddenly moved to Steam somewhere in the mid-2000s because a 1 click download was even easier than a 5 click download.
People will still pirate games for whatever reason they consider appropriate. Steam has dominance in the market - that's has a direct impact on number of sales for a product wholly released through Steam (as CiV was, as far as I'm aware). Steam's success is self-sustaining
now, based on decisions they made
back then (in the early-to-mid 2000s).
My reasons for abandoning piracy (slash never being a fan of it in the first place) was entirely moral, for example. I didn't move to Steam because I thought "hey, this is convenient" (it's also not one click, nor has it ever, because the purchase form alone hasn't really changed in years and is a multi-step process). I started using Steam because there was games on there I couldn't get without using Steam (ironically, the criticism people level at more modern competitors. But again, pushback against Steam for the same thing doesn't really materialise in popular gaming culture. It's for some reason accepted).
All of us can trade anecdotes until the world ends, right? Steam might've converted former habitual pirates into active consumers. It might not have. It might have done on a selective basis so long as the gamer in question didn't want to stick it to whatever developer or publisher. I don't really see it as relevant to the core argument of Steam being a DRM platform that exists to lock-in consumers as much as anyone claims its competitors do (which is the core dissonance that I'm trying to point out in my posts. I'm not trying to make the same arguments as Tim all the time, so I'm sorry for hijacking a bit there).
To take your latest post at the same time - Valve having market dominance (I prefer to use "monopoly", but that's an aside that tends to gets peoples' backs up, and might technically not be true given the past year or two market-wise) is exactly
why such competitors can't capture more market share. They have to occupy niches (like GoG does, with its DRM-free approach - which will also come with caveats, mainly legal presumably, as well as patch / maintenance complications), or they have to forcefully compete (like Origin did with EA's own games, and like Epic is currently doing).
