I regret buying the PC version of Pirate Warriors 3. The graphics appear to have been downgraded from the PS4 version, some controllers don't work properly, it randomly crashes(Only happened to me during one mission, but it crashed multiple times), no online multiplayer, reports of corrupted saves, and I've seen a few people claim to have run into a glitch where they get kicked back to the main menu when trying to play certain missions, among other strange glitches. There doesn't seem to be a patch on the way, either.
Figured I'd warn anyone interested in the PC version. It's not totally unplayable, but it's frustrating to deal with. Super fun when it works though!
