No revenue estimate for GOG — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $80.6K — a different platform, not this one.

Beyond Shadowgate

Overview   The original design of the never-before seen point and click adventure is being brought to life after 30 years in the vault - Beyond Shadowgate!
