I stumbled upon this old thread recently... I really like replaying some good adventure games, so here is my list of TOP 5 replays
1.
The Last Express - many many times, I cannot count it even if I had 6 hands...
2.
Atlantis: Lost Tales - at least 5 times (not anymore, cause under XP it kicks you out after inserting CD2, sad...)
3.
Gabriel Knight 2 - 3 times, I think
4.
Broken Sword 2 - 3 or 4 times
5.
Black Dahlia - 3 or 4 times
