Since I know you at least somewhat like roguelikes due to Dredmor, if you're in the mood for that kinda thing and desperate for some gaming (And haven't already played them, naturally) Rogue Survivor and Doom RL might be worth checking out. Both graphical roguelikes since I dunno if you're ACSII averse.
http://doom.chaosforge.org/ Doom RL is way more polished and easier to get the basics of than Survivor, and has some damn fine combat for a roguelike. Has multiple viable character builds depending on skills and equipment which is nice.
http://roguesurvivor.blogspot.com/ Controls a bit clunkier than Doom RL but has a nice grimdark zombie apocalypse feel to it. Have to sleep and eat, and time advances in the world constantly. Non-canned food will spoil after a while, survivors will get rarer/more desperate, zombies will get more numerous and tougher, and gangs of biker raiders will show up occasionally. Even had some alternate game modes that adds infection, so you and/or your companions could get infected with zombie-itus. Mentioned it in the Zomboid thread as far better than Zomboid, and by god it is. Still could stand to have a bunch more work done to it but it's fun enough I'll play a game or two occasionally even now.
And actually what the fuck, I'll throw a few more good freebies at you since I'm on a tangent now.
http://spelunkyworld.com/original.html Spelunky. Commonly called a roguelike platformer due to permadeath and randomized map. Really damn good, and balls hard.
http://www.desktopdungeons.net/?page_id=11 Desktop Dungeons. More puzzle game than anything, play through quick randomized dungeons with a hero of whatever class and try to kill a boss. Really simple to pick up and addicting.
For some reason I've got a feeling I've already pushed some of these games at you before, but I'm not sure. If I have I apologize for being pushy, they just tend to spring to my mind as really good freebies.
