Kerbal Space Program 2 has a big pre-launch issue: Windows registry stuffing

When it comes to early access games, the only thing harder than code and quality assurance may be setting expectations.

Kerbal Space Program 2 was initially announced for 2020, then, after a whole bunch of development shifts, arrived in early access in February 2023—a bit too early, as suggested by player feedback. There were complaints about missing features and missing tutorials, but now there's an issue with having too much of something: Windows registry entries.

As detailed in a bug report, Kerbal Space Program 2 (KSP2) drops lots and lots of "PqsObjectState" entries into the Windows registry. The initial bug report offers a 322MB text file of them, to the point that the game started throwing "PlayerPrefsException" errors and refusing to load. The issue seems to be with how the game is using the Unity engine's PlayerPrefs game preference storing system.
