In BG3 :
Approach the bookcase. Click the bookcase...loot or no loot. Click again next to the bookcase loot or no loot, move to the table, click the table loot or no loot...etc....
It feels...archaic and LAZY in comparison (game system wise).
I think I only disagree with your phrasing. "Archaic," yes, but "lazy" - I don't think so. I think looting is an undercooked feature in BG3, one of those things that definitely needed more polish, but they couldn't afford the time to circle back around to before launch. The good news is, they haven't just been sitting on their revenue from this game, and they actually seem to be using a not insignificant amount of it to service this game post launch. They aren't just using it to build new revenue streams. I fully expect that looting will be overhauled in a future patch, after they finish taking care of what they consider to be more pressing issues with more core features.
