StingingVelvet: The "no DRM ever" policy is everywhere on the site, including the Galaxy download page. Some have always freaked out and worried it might change any day now, but I don't see how GOG could ever do that considering the big deal they've made out of it...
Well, they made a big deal out of a lot of things they later abandoned:
One world, one price (abandoned for regional pricing).
All games available everywhere (until they introduced region blocking)
Only complete editions with all extras included (now they sell DLC and extras have to be bought extra)
Galaxy always optional (it isn't for Gwent)
No micro-transactions (...Gwent)
StingingVelvet: As for Gwent, I don't know enough about it to comment really, but obviously certain genres and game types have DRM inherently due to their always online nature.
Wrong. This may be news to you, but there are multiplayer games where the players can host their own servers or play via LAN. Sure, you don't get a common, persistent world for all players then, but I, as a player, want to have the freedom of choice. They could have implemented that option in Gwent easily ... but then they wouldn't be able to sell their micro-transactions.
