As much as I love old school adventure games (even though Grim Fandango was 'modern' by comparison, at the time) it is my shame to say I've not played it, nor any Monkey Island game. Must rectify.
Not only that but the banter between the characters in SR3 is always fun to listen to, they sound like they are enjoying themselves and it's contagious for me as a player.
I'm still playing through the main SR3 story and having lots of fun.
Now, the Jagged Crown... or an Ancient Nord helmet, those are badass.
