Desktop Adventures and what is possibly the best adventure game ever (though it really isn't), Fate of Atlantis. I must have played all three paths at least half a dozen times, the puzzles in parts one and two are great (once you get to atlantis it gets boring, but hey), the humour is funny, the music is great, it's a brilliant game. LucasArts is the best gaming company ever, you know...
Yeah, I love the Fate of Atlantis... and yeah, the puzzles are great... and yeah, Atlantis itself is boring, although it was fun when I got there the first time!
