Deleting old game installations

I was poking around my HDD, and found multiple folders in the steamapps\common. I assume they’re safe to delete manually, but I’m not sure whay they’d even still be there. Any thoughts?

I’m assuming they were used by earlier, deprecated versions of Automation - most likely the Kee engine version that was replaced by UE4-based builds several years ago.

Yeah, nah. They’re 4.21 and 4.24.
