*votes for DotT, Jazz2 and Tyrian 2000*

Dude, you gotta be crazy not to vote for DotT, that game took up more years of my life than jj2 did! oldsk00l all the way!

EDIT: Didn't vote for Sam & Max cuz I havent played it yet
If I did, I'm sure it would get my vote, I'm just a sucker for old lucasarts games.
