I dunno. It could be suicide to start throwing up paywalls to games people have already purchased. Maybe they'd take a more subtle approach and would limit downloads or start throttling, whichever the more irritating, driving members to pay a small fee p/m for the unrestricted access they're used to.
It is a free platform after all offering unlimited downloads to over 100 million active users.
No probs with gog I think they're alrite reviving older games and always heard good things. I meant to query the download thing as I had no idea, just assumed they'd always ran through their launcher. So more kudos to them if you can run gog games independently.
Can you name some games? Genuinely curious to know, assuming you're not talking about betas and early access
As for multiplayer games, no, me neither. Unless there's a large clandestine player base to engage with like WoW had, I don't see the point. For SP, I would imagine if you don't mind all the inconvenience that comes with losing the nice perks/features you get through Steam, alongside some stuff in the game itself like SP leaderboards, it's pretty much a no-brainer. They can sometimes run a bit better too. Even Ubisoft used a RLD cracked exe lol.
Of course some people buy games as they like to support their developers, who might argue the moral obligation concerning this practice.
