I got almost to the end of Grim Fandango and it bugged and I couldn't find the thing the walk through said I should! It was very frustrating.
Watched a friend of mine play some of it. All I remember is the game repeatedly saying "pistachio!"
I liked how it came with a pair of blue and red anaglyph glasses that are only used at the very end of the game. I had lost them before I got there years after I bought it, most of the puzzles were complete bs.
John Cleese as the bomb was a particularly fun role. This game just had a ton of personality.
