Maniac mansion, zak mckraken (which i'm currently playing on the phone), loom, monkey island, day of tentacle, sam & max, indiana jones, full throttle, the dig (one of my old time favs) and even the newer ones like grim fandango.
Loved them all. That company was a major part of my childhood and one of the main providers of english vocabulary. One could learn so much from those games. Too bad they just went extinct. It's the indie scene that's keeping them alive now, and hopefully that will last longer.
By the way. For those "fans" out there, you can get SCUMM VM to run on your phone (android of ios), and get free roms off the net (free as in abandonware not pirated free). It's actually quite fun even on a small screen.
