Stone Soup, DoomRL, or Brogue. These have improved interfaces, comparatively transparent mechanics, and tend to discourage scumming.
The most popular roguelike in active development, Crawl's success stems from a design philosophy supporting clarity, consistency, and accessibility. Thanks to an improved interface, exploration improvements, and a tutorial mode, Crawl is more accessible than most while retaining its tactical and strategic depth, and substantial differentiation between race/class/god combinations allows for true variety. Dungeon levels are persistent, like Nethack, but huge and scrolling, like Angband. In short, this is probably the link you came here for.
Evolving from Hack, Nethack is Rogue's most direct descendent and the rogue by which virtually all others are judged. Nethack's slogan is "The Dev Team thinks of everything," and in effect, every item and player action has clever, sometimes devious uses depending on context, leading to extensive reliance on spoilers and what some have termed "feature-itis". "-Hack" games are known for persistent, single-screen levels and shops that exist within the game world. Development on the main branch has stalled and possibly ended.
*Note that nethack was last updated in 2003. Nitrohack is an in-developement fork that fixes some bugs and has made several GUI changes that make the game experience much more enjoyable while still being true to the original game. Get the latest version here: http://nitrohack.org/
Moria's descendent, the other pillar of the roguelike family tree, and the classic that inspired the Blizzard game "Diablo". Borrows more liberally from Lord of the Rings, as evidenced by the name. "Band" games, in contrast to "-Hack" games, are known for huge scrolling levels that disappear after you leave, frequently begin on a "town level", and feature shops that break to a menu screen. Coupled with more items typically having only one obvious use, -Band games tend to be longer and grindier, but less spoiler-reliant than Nethack variants. Angband is the most frequently modded roguelike. Development has been resurrected.
Featuring the T-Engine, this Angband-based roguelike has unlockable content and support for player created modules. Unusually bloated and slow compared to its lean predecessors and contemporaries. Combat is based on cooldowns not unlike popular MMORPGs. In active development, Crawl vs ToME comparisons continue the Nethack vs Angband legacy.
A deeply complex roguelike featuring a pregenerated world map, quest tree, multiple endings, and unparalleled character generation system. Features single-screen, persistent levels like Nethack, but also contains a surface world and towns ala Omega. ADOM is notorious among the major roguelikes for never having the source code released, and ADOM 2 is being developed with a controversial "crowd funding" system.
A design philosophy influenced by Stone Soup and what the original Rogue might look like if it was still being developed today-- simple yet elegant, and very, very cruel. No tiles, but ASCII is unmatched in clarity and beauty. Not large enough to be considered a "major" roguelike, but arguably the better for it.
It's DOOM! Guns, health kits, levers, more guns & a new graphical update so there's lot's & lot's of blood! All as a turn-based roguelike!
Features deep character system and interaction mechanics based on DnD with some significant tweaks. Strives for high levels of depth and complexity akin to PnP, but held back by slow development and bug issues.
Where Angband nods to Tolkien, this variant explicitly exists in Middle Earth, with strong emphasis on tactical combat and discovery.
The most notoriously brutal roguelike, featuring a fiendish sense of humor. Strictly for masochists.
Post apocalyptic survival game with detailed inventory and combat systems and surprisingly interesting/expansive crafting.
The original roguelike! Rogue's use of ASCII characters allowed for true screen orientation in a CRPG, making it a landmark in gaming history and paving the way for virtually every video game "RPG" since.
The Rogue spin-off that would eventually become Nethack, so it plays like a sophisticated version of the former or a very crude version of the latter. An important benchmark in the genre's development.
The first roguelike with a "town" level, but not the obvious predecessor to Angband (that would be Moria). Level generation is more mazelike, but does not yet scroll.
The developers of this project re-coded the roguelike "Larn" from scratch and the result is a more stable and aesthetically pleasing version of a classic.
The predecessor to Angband and the historical equivalent to Hack. Map scrolls, but only when character approaches the screen's edge.
A somewhat obscure but very in-depth roguelike which features a world map, a questing system, and a good sense of humor. While clearly an influence on ADOM, differs from Hack and Moria in that it remains unique and therefore has appeal beyond historical curiosity. In other words, play this one.
The original version of Crawl as designed by Linley Henzell. More generic, grindy, and outright brutal, it may feel somewhat primitive compared to Stone Soup, but still holds its own against Nethack and Angband.
