I think it is fine if you install the games on a PC that
Doesnt contain any personal data and is only for playing PC games
Is never connected to a network, public or private (always offline)
Otherwise I wouldn't recommend ever installing HyperVisor, and if you do, wipe the drive and reinstall the OS. Maybe even better, wipe the drive, destroy it, and then replace it with a new drive. That is the best way to know for certain there is no security compromise on the drive.
Super Mecha Champions, when the servers were still online. Such a fun game, genuinely fun gameplay.
Second place is either Stellaris, Helldivers 2, or Halo CE.
