Very interested in your thoughts on the main plot. I felt it had a lot of holes, unearned moments, and tone issues.
I definitely have a lot of thoughts. This isn't really the place to go into them, so let me sum up. Some of my problems are just personal taste - I've never been particularly interested in illithids and their lore, and their gory aesthetic is not appealing to me. Also, Larian's design decisions surrounding multiplayer and Origin characters seem to make it nearly impossible for them to create a compelling narrative centered on a "Tav", which is all I ever play. But beyond those things... well, yes, there are plot holes, lore failures, nonsensical moments, etc., but if I'm really caught up in a story, those are things I can forgive or ignore. Unfortunately, as I started Act III, I found myself gradually losing interest. The very climax of Act II may have been the turning point, it just... didn't feel as epic as I was anticipating.
WotR, on the other hand, was so much fun the whole way through. I was 100% invested in my character, in the story, in an awesome, epic adventure across the planes, touching the very realms of the gods, with an intensely personal thread woven through it all. That game really felt like a sequel to the BG trilogy at times, despite being entirely unrelated.
