People poi ting to OG baldurs gate or NWN games and daying 'well THEY did it. Why cant Larian' is making a false comparison.
For one, you needed several games to reach a lvl that would be comparable with dnd 5e lvl 12+. For another point alot of spelle and game mechanics have changed from edition to edition.
Sure some things like timestop or wish stayed roughly the same but that doesent count for everything. Likewise when youre at that lvls of power you are generally fighting waves of demons or devils or other powerfull entities that would require such a powerlvl.
The bg3 campaign doesent handle that. Maybe an expansion will but so far lvl 12 is the max.
Pnp campaigns are also written with certain lvl limits in mind. I think Larian just screwed up the xp requirement somewhere or made to many quests that conpletionists can do if people reach lvl 12 so much faster then they reach the end of the game...
Limiting the amount of content wouldn't have improved anyone's perception of value.
This game isn't cheap relative to others and we only got a half-baked potato.
Fact is, 6 years to turn out BG3 is embarrassing arriving as it did with more bugs than an old fashioned pest strip and broken storylines.
I don't think you needed several games to make enough leveling content, we aren't going to live long enough to see several games, but you do need planned expansion, of which there is apparently none.
