As @Gel214 said, challenge scaling exist in PNP 5e too, the DM is constantly adapting the CR of the enemies to match the power of the party, or the game will lose interest for the players, and combat became too one-sided.
That said if it´s made like in Bethesda videogames It can be frustrating, just as the others in this thread said. In most story-driven RPG you have the scaling because they calculate the max level you will have when reaching certain point in the story and plan the encounters accordingly, something that is not feasible in sandbox-y games like Skyrim or RDR. I assume that would not be the case in BG3
I've never played in a PnP campaign where the DM scaled a monsters CR. If the party is too high of a level for goblins, for example, they don't make standard goblins stronger, they add in higher CR monsters like ogres, worgs, hill giants, etc. That isn't the same challenge scaling we are talking about here. We're talking about the system like in Skyrim where ALL enemies are you level, whether they are elite guard or lowly peasants. The level scaling that BG3 SHOULD have is where, depending on the difficulty you choose when you start your game, they give you monsters of the CR that you picked. I don't want to see normal goblins at level 5 that are CR 5. If there is a goblin boss, or goblin shaman, that is stronger than a standard goblin that's cool-beans...they are. but not the scaling we are talking about here.
