Damn I forget this MI2 puzzle you guys are all talking about. I can remember being stuck in a few places for a while but thats part of the fun. I wasn't all that fond of monkey kombat from the last MI game, ended up writing up a table to figure it out which was a pain in the ass. I still think the best was insult sword fighting in MI1. (dunno if you would call it a puzzle but it was a favourite of mine. Then well it just became one big long run on joke in the other games.
Insult Sword fighting was great
and that Puzzle with the guitar(or something like that) in Curse Of Monkey Island funny
