the new humble indie bundle (numero 5) is just awesome!
www.humblebundle.com

after a number of so so bundles we now got
- bastion
- amnesia: the dark descent
- limbo
- psychonauts (from doublefine)
- superbrothers sword and sorcery EP

not really RPG (except for bastion), but i didnt think it worthwhile to create a new thread for every indie bundle out there.
