I recall another game... a Sierra game, Torin's Passage. It took me years to find it again. You travel through the different realms under the Lands Above, pretty much a Journey to the Centre of the Earth-type dealie. Also, Mechwarrior. I never played it, my dad did, but I learned to love walkers/mechs from that game.
I never played the Myst series, but it sounds like my kind of game. I should see if I can get a copy.
American Mcgee's Alice, like I said, was one of my favourite games until I looked more into the series and discovered the dissimilarities.
