Angband

Angband is a free, open-source roguelike with loads of dungeons for players to explore in their quest to find and destroy the fearsome Morgoth, the Lord of Darkness.

This game is loosely based on the works of J.R.R. Tolkien, and began as a sequel to Moria, one of the first roguelike games to be developed. Originally, this game was designed to expand on Moria's storyline, as well as add more enemies and items to create a more solid game experience. Over time, however, it evolved to become a mainstay of the genre.

Angband offers players loads of character creation options, so many that creating your character can take significantly longer than similar games. Once you have your hero, you'll run into all the classic features of a roguelike game: procedurally generated dungeons, permadeath, and a high level of difficulty.

One notable difference between Angband and most other roguelikes is how easy it is to change the graphics. This game offers various tilesets, so you can choose whichever one suits your tastes with just a click.

Angband is one of the best roguelikes available for Mac, not only because of its solid, engaging game experience, but also because of its exceptionally easy to adjust interface and graphics.
