Eurogamer has a nice review up, so I won't bother. Read it here. http://pulse.me/s/14DDf
If you've been reading my columns in the past for TNIE or on BossFight, you'll know that I'm a huge fan of Nethack. Dungeons of Dredmor is the coolest roguelike to come out in ages. There's something to be said for wearing a traffic cone and throwing cheese at monsters. And dungeons with Coke machines.
Go play it. Now.
