What are your favorite roguelikes?

Castle of the Winds. Played it SO much with my dad when I was a kid, good times.

Dungeons of Dredmore, such a good game

1. Dungeon Crawl Stone Soup
2. Dungeons of Dredmor - for humor and variety of skills
3. IVAN - for being insane
4. Steamband, some other angband variants [mostly played old ToME while it was still an angband variant]
5. DoomRL
6. ADOM - though now I consider it too repetitive and linear - not enough artifacts, tedious (pre-\post-)crowning, but still awesome

And as an honorable mention: Spelunky and The Binding of Isaac

As Stonesoup has already been mentioned I'll have to go with Dwarf Fortress although it's long since elevated past the point of "Roguelike".

the binding of isaac! :)

BoI

Cardinal Quest and Hack Slash Loot

I think the only Roguelike I've played was Hack Slash Loot, I liked that one.

Nethack

Really digging FTL: Faster Than Light, and Desktop Dungeons.

Still Angband and some good variants -- I played it for several years straight I think. I like Nethack very much, but Angband fits me better in some ways. Crawl is very good, too. Ah hell, I really love quite many of them, but Angband caught me good when I was a kid.

Pokemon Mystery Dungeon: Explorers of Sky

Dungeons of Dredmor, Binding of Issac, and Spelunky, though the last two are really rougelike-likes. Speaking of like-likes, I wouldn't mind a randomly generated Legend of Zelda game. Hold on while I go beat Nintendo over the head with that.
