I’m playing through BG3 with a good friend too, we’re actually planning on doing another, wildly different, playthrough when we’re done with this one. We’re playing sorta chaotic/neutral good right now and intend to do an evil campaign next with different characters and classes and possibly even modded.

Now I obviously haven’t tried it yet but the game has so much hidden stuff, branching paths and different-to-play classes I’m fairly confident you can play it at least twice and have an almost entirely new experience!
