Have you ever played Rogue-Like games? NewGrounds front paged a new one called Rogue Fable II: http://www.newgrounds.com/portal/view/690180 that I really like. I sort of made one myself a long time ago: http://www.newgrounds.com/portal/view/540262 It's not great. My favorite is probably Dungeon Crawl: Stone Soup, but it's very hard and complicated and I don't play it so often anymore. Prospector is also fun, it's in space. Anime Angband was also a hoot.
Seems like there's a certain revival of the Rogue-likes, I see a lot of games advertised as having "rogue-like features". Usually, they really mean "diablo-like" or just randomly generated. Like FTL. FTL is a great game, and very random and very reminiscent of rogue-likes, but I feel like what makes a game rogue-like is Rogue's grid-based exploration, so I get kinda miffed that FTL calls itself a rogue-like. I'm ranting now, aren't I. Better stop.
Did I ever tell you about the time I redrew NetHack's sprite-sheet so that the playable characters were all naked ladies? Good times. Can't share that story on most of the interwebs, but I feel alright with you guys.
