depends from player to player, taste to taste.
last adventure games i played were "dreamfall:the longest journey" and "still life". They were pretty good if you ask me.

altough reviewers give dreamfall low ratings, it was a great game(even better if you played the first one). There were a lot unanswered questions at the end of the game, it feels like there will be another game that continues story, but actually small hints back to first game answers a lot of questions. tho waited long for the next game idk when it will come out.
