Hmmm... I see this thread got resurected yet again... (first thread I ever actively posted in on Abandonia).

I still say that classic 2D adventreus are my favorite.

There were some mentionings of fan made adventures and lately more and more good 2D point'n'clicks are made by the fans of the genre. It took me a really long time before I got convinced that at least some quality can come from it, so here are my personal TOP 3 FAN MADE adventure games:
-The White Chamber
-The Infinity String
-Stargate Adventure

White Chamber was very good indeed.
Stargate Adventure showed good promise but felt way too short IMO.

Well, the White Chamber really isn't that much longer. You should try The Infinity String (it's the one that finally got me convinced that the AGS made games can be good).
