Definitely want a serious RPG that also takes itself a little bit more seriously, too. Story driven, D&D party gameplay with co-op multiplayer as an option.
In my PnP group we also liked to stage fights between our characters, but that was done entirely out of character, outside the campaign. Goofy screwing around and PvP, and a Baldur's Gate campaign are two different games. They shouldn't be mixed.
And let's not pretend you could ever actually play BG3 competitively (like 2v2) in such a tight and controlled narrative that takes place on theme park maps. It would be a total mess and wasted development time.
