Unfortunately, my family and work responsibilities simply won't allow me to participate in a multi-player game - my schedule is just too bonkers.
That being said, regardless of the fact that I already purchased the game, unless I can play with a party of six - whether implemented by Larian or via a mod, I won't be playing. I'm lucky to get one play-through of a game - multiple play throughs are impossible - if I can't maximize the content available in that run, I'll invest my free time elsewhere, and sadly miss the Forgotten Realms.
I felt that way after play-testing the game and feel even more strongly about it after reading the experience of those using the mod. It has become a red line for me at this point.
