Some favorites for me: Sandworm, basically solo Tremors (1990) where you need to dynamite a giant sandworm $2CAD

Escape the Zone, Roadside Picnic/S.T.A.L.K.E.R inspired $5CAD

Under Falling Skies, 9 card PnP solo board game. It was also part of a competition that happens yearly, I’m sure there are other cool submissions.

Chzo Mythos, a point and click horror series. Thats the Linux version page but the Windows ones should be there too.
