If you don't mind some puzzle solving and the fact it's a point and click adventure game, there is Beyond The Edge of Owlsgard. It can be completed in a couple hours if you have played it before, but took me so much longer since I had no prior experience.

There is also Brok the Investigator, which is a choice based game where your actions lead to one of something like 6 different endings before, supposedly, getting the cannon ending or something along those lines.
