"Brogue is a Roguelike game for Mac OS X, Windows and Linux by Brian Walker." It's REALLY good: stripped-down and straightforward, as Rogue was, but with nice mouse implementation and a lovely auto-explore mode. Really rather nice.

MeFi thread spun out of my Roguelikes post; some great comments and insight, and what a cast!

The beginnings of an encyclopedia for Roguelikes; some useful stuff in here, given current interests.

"A favorite on college Unix systems in the early to mid-1980s, Rogue popularized the dungeon crawling computer game dating back from 1980 (and spawned entire class of derivatives known collectively as "roguelikes"). gandreas software now presents the classic for the iPhone/iPod Touch." Oh god, Rogue for the iPhone. Unusual gestural interface, but it's a perfect port, and brings back memories of being 7 all over again. Needless to say, I installed it immediately.

"Dweller is a simple roguelike targeted for Java enabled mobile phones" lovely - straightforward, classic ASCII Rogue on your j2me mobile. Two thumbs up!
