Yes, I can grasp what you mean.
It is a role-playing on a different level, and with that it has its own merits and shortcomings.
Baldurs Gate 3 is a role play on a lower, more character centric, level which limits the freedom of the player but allows for the game to have a tighter, more interconnected storytelling.
Starfield is a role play on a higher, more player centric, level which allows for way more personal freedom of the player at the costs of having a story with pieces flying loose through the air, so to speak.
The venn diagram of people who like both of those types will most likely don't have a huge overlap.
Neither of those games are bad, they are just fundamentally different.

Nvidia GPUs are known to be problematic in Linux, not only with Wine/Proton
