Penny Arcade Adventures: On the Rainslick Precipice of Darkness 3
I don't think there's a thread for this yet, but it's coming out Monday so I thought there should be one.
Or it WAS coming out Monday. Robert Boyd, co-creator, was interviewed on Active Time Babble (good episode, gender and LGBT issues in RPGs) revealed that while the PC version will indeed release Monday, it may be a little while for the XBLIG release because someone found a very minor glitch that forced another attempt at certification, which can't be submitted til a week after the failure. I really think I should get around to playing the first two episodes, so maybe this'll be a good chance for me to do so. Unlikely though, as I bought on Steam but never play any damn PC games.
He also revealed that there will be a fourth and final episode starting development after this, targeted for release around PAX West next year.
Here's the Giant Bomb Quick Look of the game (direct link)
If you buy in the first week you get a copy of Zeboyd's last game, Cthulu Saves the World, for free.
If anyone else has something they'd like added to the OP let me know.
