I always finished Space Quest 6 with 498 points. Some people said that the maximum possible points are 500. There is a points list here: http://www.spaceques.../sq6/pointlist/ But there are two mistakes: __________________________________________________ Go to the Orion's Belt and kick in the basement door - 1 I can't get this 1 point. Only this one works: Open the basement door - 3 __________________________________________________ Untangle the hookah hoses - 3 I only got 2 points for this action. __________________________________________________ The maximum possible points are 498 or 500?
