Latest and greatest Humble Bundle
is up. The last couple have been iffy (I mainly got them for the Android app versions) but this one is pretty golden.
Amnesia: The Dark Descent
Superbrothers: Swords & Sorcery EP
-- and pay over the average to get --
Bastion is an awesome game. I haven't played but heard Limbo & Psychonauts highly recommended and Amnesia is the the go-to when someone asks "Name the scariest game you can..."
The 'worst' part about this bundle is that a lot of people probably own some or all of these already because they're so well regarded. If you don't, this is your chance to get them inexpensively.
