I thought you might want to take a look at Dungeonmans, which just put out a new playable preview (along with a Kickstarter). The game is a graphical roguelike game, so it's a very tough dungeon crawler, but it has hilarious humor and a persistent overworld, and lots of potential. Unlike most roguelikes, it has tactical combat and a bunch of abilities, and you can build your own class. If you die, some of the things you did carry over to your next character in the Academy.
The preview build is a pre-alpha version, so there are still some bugs (make sure to read the F1 help and use Spacebar to open the menu), but it's fully playable up to level 12 and has a special preview endboss. You can get it here (make sure you have the XNA binaries installed, you can get them from a link on the page):

The game's been in development on and off for a few years by a programmer who used to work in AAA games who is going indie. I'm hoping that people who enjoy roguelikes will get a chance to see it. If you do post, it would be awesome if you could post about the kickstarter, too:
