In a lot of situations, I feel like BG3 plays more like a TRPG than a video game D&D. Which is fine. I like TRPGs a lot but a TRPG and D&D are wholly different beasts.
And please recognize that this is a COMPLETLEY subjective point here so I'm sure you and others might disagree. But what I mean is that BG3 rewards you and I would say even implies you should go into encounters, seeing exactly what surprises await you (Like surprise additions to fights or enemies doing weird things to the environment you might not realize beforehand) and reloading and doing the fight again with new knowledge. That is decidedly not a thing in D&D, you don't rewind after you see some twist the DM makes.
And yes I understand that its a choice you as the player individually make, but unless you have a particularly mean DM for no reason, usually the DMs are not trying to actively just kill their players as much as they possibly can, which it feels like BG3 does in
certain fights. If I'm doing a fight in BG3 and suddenly the game just spawns 5 enemies right next to characters I'm keeping out of melee range without me having any foreknowledge that it's about to happen, that doesn't feel interesting or fun to me. It feels like a video game. That's where the illusion of this just being Dungeons & Dragons breaks for me. And I deduct a bit from the overall score of the game.
