I just had probably my 10th instance of the game being unable to launch. I know how to fix it, though it takes quite a lot of time and I don't have an infinite amount of that available. Every time the XBL network experiences an issue, which is quite frequently as of late, it affects PSO. Every time you close the game, you run the risk of corrupting data thanks to it running off the Microsoft store. Have a crash? Good luck restarting, your game is now uninstalled yet still taking up space!
PSO is 8 years old already, it should run incredibly well as the JP dev team has had a pretty long time to work out the bugs. There was one fairly major issue at the PC launch aside from install issues themselves (which is due to the Windows store), and it got addressed, a date set for it to be fixed, and it was patched on the exact date stated. The problem is Microsoft, and I really REALLY wish Sega would remove them from the equation already.
Steam launch when?
