We have a huge megathread on these forums about party size that's been going since early access and to which folk are free to contribute further: https://forums.larian.com/ubbthreads.php?ubb=showflat&Number=672266&gonew=1.

I'll therefore lock this thread to try to cut down on duplicate discussions.

"You may call it 'nonsense' if you like, but I've heard nonsense, compared with which that would be as sensible as a dictionary!"
