One of the most common complaints I hear about Bg1 and 2 when people go back to play it is that it "hasn't aged well and it feels like work to play it".
It's a recurring idiocy people say about a lot of older games.
Frankly I feel that the only aspect of BG2 that didn't "age that well" is its technical obsolescence: natively designed around a very low resolution, with an abysmal default frame rate, etc.
And you could make an argument for the inventory system being a bit more cumbersome that it should be. Which ironically enough is a complain that can be applied to BG3 as well.
Then you have slightly modernized takes on the same formula (PoE 2 and both the Pathfinder games) proving almost everything of the core system can still work just fine to this day.
