Depends whether you are a Sierra fan or not. And if you are a Sierra fan and have never played these games then you are missing out! However you do need a damn good eye when playing these as some of the puzzles are evil!
Besides they are more of a classic than some of the games on the list such as Holiday Poker, Turrican 3 (shocking as Turrican 1/2 were great), Scooby Doo and quite a few others I can mention.
Depends on what you like I suppose.
