The current Humble Weekly Bundle features six roguelike games. Vertical Drop Heroes HD, A Wizard's Lizard, The Nightmare Cooperative are the primary components. Beating the average (currently under $5) adds Road Not Taken and early access to Delver. Pay at least $8 to gain Heavy Bullets.
I personally speak for none of these games, one way or the other; I've not heard of any of them before, and with the number of self-proclaimed roguelikes available on Steam proliferating lately there is no way I can test them all, even if I had the money to scoop them up (which I do not). I mention them in case one of you thinks they sound interesting. Check them out and see if you like!
