I really liked Grim Fandango. Not all the way through it, and probably not going to finish any time soon, what with Kingdom Hearts III and Super Smash Brothers Ultimate in constant rotation, but I lost a lot of hours to Grim Fandango. The puzzles are sometimes easy, sometimes impossible without Google. Great music and the story moved along at a good pace. My fiancé adds that if you liked the 80s LucasArts games, you'll appreciate GF.
If you've already got a backlog, GF will help add to it. ;)
I found the switch that opens up the glass. I've been able to get into the room with the dead man, but I can't find my way out of that room. The door there is the only way to get to where my uniform is; and I need that.
