Indiana Jones and the fate of Atlantis taught me that hot air balloons are extremely easy to fly and to steer. I won't believe anything else unless it is in a better point and click adventure game. Hint: there is no better point and click adventure game. Day of the tentacle comes close but doesn't beat it
I dunno, man, I think KQ6 beats Fate of Atlantis. QFG4 as well, and one or two Space Quest games. I could go on, but that seems sufficient to disprove your thesis!
I'm actually with you on the hot air balloon thing.
