Cthangband

Cthangband is yet another Angband variant, but what makes this version unique is that it's inspired by H.P. Lovecraft's Myths of Cthulhu. This means this version has new races, locations, and a new magic system, all at the same difficultly of a typical roguelike.

This game is set in the Dreamlands, a surreal fantasy world from some of Lovecraft's most popular stories. This world is full of dungeons and monsters, as well as a healthy dose of H.P. Lovecraft's signature cosmic horror.

Cthangband offers players dozens of character options, so many that creating your character can take significantly longer than in similar games. Not only that, but since this game has new races and character classes that are not included in Angband, even roguelike veterans will find something new.

This game has been in development for over twenty years (which is relatively common for roguelike) resulting in loads of carefully designed content. Overall, Cthangband is an excellent variant of one of the best roguelikes in video game history.
