And Fate of Atlantis! I got that three-pack myself.

DOTT and FOA were great games (I'd say I think FOA is the best LucasArts game I've played), but I still haven't gotten to play much of Sam & Max.

The only problem is that the DOTT version is the really, really old version. I'm not usually someone who cares about graphics, but the old version's graphics really are kind of ugly.

It's probably because I first played MM on its Nintendo port.
Anyhoo. MM's a good game. It's one of the few LucasArts games where you can die, and IIRC it was the first (or at least one of the first) adventures to have true cutscenes and multiple endings. And it's got plenty of weird humor.

And it originated the awesome SCUMM engine. How can you go wrong with that?

Peace & Luv, Liz
