I must admit I have found BG1 to be the most lackluster of the trilogy. I liked BG2 quite a bit, though. BG3 seems great lorewise. The companions in BG1 were quite basic, cartoonish even and fortunately, BG2 added a layer of complexity to them. I love moral ambiguity and BG3 offers far ore freedom to pursue your goals. Part of the changes in enemies come from the 5e ruleset where in general low level characters have a bit more chance against stronger single monsters than in earlier editions. Overall, BG3 is on the way to topple BG2 in my ranking (if they might reduce the number of explosive barrels, it will be even better )
