StingingVelvet: Cosmetics for making an account or whatever are not DRM. I get why people dislike it, I dislike it, but it's not DRM.
DRM is more about how you access something than the "importance" of the content. There's zero practical reason why the content isn't just included in the game. There are other games here like QUBE 2 where "it's only cosmetic skins" (Classic QUBE 1 Glove Skin) are still made available to everyone offline via a small sub 10MB offline installer (
see gog.db entry).
This may be seen as relatively unimportant content to many, but we all know exactly what the issues have been over the past few months with GOG's incessant "over-pushing" of Galaxy, this isn't an issue that exists in a vacuum and is very obviously part of an ongoing "slippery slope" given other recent events, and the constant gradual "gating off" of single player content behind not really 100% "optional" clients by the actual owners of the store here is an entirely 'political' move here that's no longer about claimed 'misunderstandings' with 3rd parties as with No Man's Sky. (Points to Hello Games -> "they did it not us" is not an excuse this time).
"But it's only cosmetics" -> "But it's only a soundtrack" -> "But it's only DLC" -> "Ah, what the hell. All that DLC requires a client, so why shouldn't the base game?..." I can see exactly where this is going to end up 5 years down the line without "pushback". Hence why "irrational" complaints here over 'trivial cosmetics' are entirely rational when looking at the "long game".
