First thing that popped into my mind too. Monkey Island, Loom, Zac McKraken, and all the other LucasFilms (but even after they rebranded as LucasArts) too.
Indiana Jones and the Fate of Atlantis is still my favorite point and click adventure. Purchased it three times too: on floppies when it came out, the enhanced *talkie *edition on CD, and then on Steam when it came out.
