The first Fallout barely had anything, but Fallout 2 sure is something else having specific perks, traits and statistics about sex, a bunch of people you can have sex with and some you can get pregnant, and you can work as a prostitute or a porn actor. Or force some of your companions to do so.
That's how denuvo is supposed to be used, doesn't mean it is how publishers do use it. The moment the game is cracked denuvo stops being useful. Doom Eternal actually launched with a drm free exe as mistake in the first place so it's never been very useful :p
Because when you are giant studio using Unreal Engine there really is no excuse for poor performance or porting. But when you are a (relatively to Epic or Sony/Microsoft etc) a tiny team building a game using the engine you came up with yourself with its roots somewhere around 2010-ish , back when 6 cores was a brand new thing and have been tweaking it ever since, you do get some slack if it doesn't multithread perfectly.
Also it's a Larian game, so not only will it have all the thousands of bugs fixed (literally, the first patch had over a thousand fixes), you'll probably get the Extended Enhanced Definitive Divine Edition that rewrites half the quests and adds a bunch of new ones.
Usually they don't. Something like Horizon Forbidden West credits almost 3500 people even though Guerilla Game has less than 500 employees, most of the rest is absolutely massive bloat from different outsourced teams and Sony departments - like the "Head of Opportunity Markets Business Operations Tim Stokes from Sony Interactive Entertainment Inc.: Global Business Operations" was undoubtedly very important for the development of the game.
As for Baldurs Gate 3, Larian Studios currently has 450 employees in 6 different locations, so they are actually around the same size as Guerilla. I wouldn't be surprised if the credits end up being well above a thousand people (D:OS2 has around 500 credits even though Larian back then had only 130 people).
