Not as much of a "game", but I thoroughly enjoyed "Gone Home". There's also "Kentucky Route Zero" and "The Novelist".

Agree with the first two (haven't played the third). "Dear Esther", too. There is some fantastic stuff coming out of the indie scene.

"Quiet Please" is a small fun indie Android title with a lot of the elements that I like about adventure games. (I have to use what with what?)
