I haven't played anything D&D 5e before, ever, and even BG2EE was quite some years ago (so my memory of it is not great). I don't think it was too hard? I mean, we're capped at level 4 currently, and I didn't manage to beat the Bulette (hehe have to laugh at that name everytime, because we call burger patties / "meatball" patties Bulette in Germany...) but otherwise, sure there were some fights I had to reload several times, but to me it feels like the current set difficulty should be standard/medium difficulty.
