If anyone stil lhas trouble figuring out what toput on the list: Wikipedia has a list compiled from GOTY-awards from magazines. The single games might be debatable, but overall the list has some good games to pick, if you forget an older game that is worth to be put on your list. Although it is a bit spotty in the 70s... Looking at that it reminds me: I still need to play Zork.
