afaik, a uPlay account was required for an Anno game here before servers shut down, and a Paradox account is required for some Paradox multiplayer and/or online features here, so that's believable.

Battletech: "Please Note: BATTLETECH uses Paradox Accounts. You don't need an account to play the campaign or single-player skirmish modes. However, you do need a Paradox Account to challenge other players in 1v1 multiplayer matches and to redeem unlock codes for Kickstarter Backer or Pre-Order DLC."

As someone not interested in multiplayer and not necessarily add-ons, I won't get too upset but I understand if others do. I guess the add-ons could be really interesting for the single-player experience. (all this assuming we don't get another Hitman situation where the majority of the single-player game requires a Bethesda account...)

Here's the thing: GOG obviously felt bold enough to allow Hitman through in its current state. What does that say about who they're trying to get money from? Are most GOG users using Galaxy even though Steam is superior in many ways (or they're using both for whatever reason)? We don't really know, do we...

It's weird: GOG will die if they drop DRM-free, the only feature setting them apart from the competition, but also, users who care about DRM-free are such a minority here that GOG can pretty easily alienate them.
