If you're planning to play split screen, get a refund before it's too late. If you haven't seen this thread yet then know it's been unplayable in splitscreen for 3 weeks now even after char creation anyway.
It's probably better to buy it later if they ever fix it for ps5 because right now there is no communication from Larian and it doesn't look like they will do anything about it. (Appart from the diehard larian fans that says that they will)
