I can completely understand your frustration, and you have my full support! The fact that the game still struggles with crashes is shocking to me. We play on the PS5 and have been waiting since release for the split-screen feature to be disabled. Especially at launch, the game had extreme freezing issues, making it almost unplayable. At some point after Patch 4 or so, we started experiencing extremely frequent crashes. And for a while now, we've been out, we've lost interest in the game. It's good, but the permanent split-screen ruined it for us. To this day, I don't know if they are aware of the problem or if it will ever be changed... I started the game solo and initially had fun, but after Patch 6, the stealth mode is broken, which is the final blow for me. We also feel that the co-op mode is being seriously neglected. We waited for half a year, and only now, after Patch 6, do we have the option to adjust the font size of books, etc. It was always so small before that you couldn't read anything. For such a small thing, it just comes way too late. Now my wife and I are done with BG3.
I honestly don't blame you. I enjoy BG3 solo, but I WANT to play with my spouse, as we play DnD together. It is bullshit that coop has been in this state for this long without even a word. Appreciate the support, we need to get this noticed!
