The latest Humble Bundle celebrates the 20th anniversary of Double Fine, the studio behind some of the most famous point-and-click adventures of all time. But as you can see, there's a lot more than point-and-clicks on offer, with 19 games available for $9 ($13 AUD).

The first tier includes "Psychonauts" and four documentaries for only $1 (A$1.42): Double Fine Adventure and the three "Amnesia Fortnight" series.

But things get serious when you pay more than the current average of $8.13 (A$11.31): "Day of Tentacle: Remastered," "Broken Age," "Brutal Legends," "Psychonauts in the Rhombus of Ruin", "Massive Chalice", and "Costume Quest" are added at this rank.

The highest rank is not much higher at $9 (A$13); for less than a dollar, 12 games are added, many of them published rather than developed by Double Fine. Among them are Rad, Gnog, 140, Thoth, Mountain, Everything, Escape Goat 2, Gang Beasts, Kids, Full Throttle: Remastered, Grim Fandango: Remastered, and Headlander.

This bundle will be available for the next two weeks.
