I like how you picked the two worst examples (IMHO).
Those are the culmination of a decade of dev experience, sure. On that front they are at least 9/10 games.
But ambition creates bloat and genericness. Those two are ambitious games, but they shedded a lot of their identity for mass appeal charm.
Elden Ring is one of the most unenjoyable and bloated FS game I've ever played. It's a huge letdown after Sekiro and unironically feels much like a Ubisoft game. Copy-and-pasted assets everywhere, samey objectives, and an open world that is too bloated and spammed with uninteresting "points of interest". They did this because open world is in vogue and because of their ambition.
BG3 is not a bad game but Larian's charm is very much absent from it. DOS1 is one of their first forays into CRPG and despite it being not so polished you can very much see the charm in that game, with a lot of humor and the classic Larian style of not taking itself too seriously. Importantly DOS1 is also pretty focused and isn't bloated with too many sidequests. The sidequests that do exist all tie in to the main plot too. Unfortunately BG3, despite its polish, is extremely unfocused and feels more like a theme park where you wander around instead of having a gripping narrative. As a result the story is one of the most forgettable ones I've ever played through from Larian.
Also I'm really just tired of the MA2 formula. It's everywhere these days. It's like none of the RPG studios know how to develop characters without using the MA2 formula anymore. It's a very inelegant formula that worked well back in 2010 but not in effing 2024 lmao.
