Stumbled across this link while googling for some things about Angband. It provides a very good introduction into the differences between Angband vs Nethack. Both games are decended from Rogue (Hack -> Nethack, Moria -> UMoria -> Angband).

COLUMN: @Play: Angband - At Last!

I'm currently playing with Angband 3.0.9 (Vanilla). The "Vanilla" means that its the original Angband and not one of the few dozen variants.

The game play is fairly suitable for all age groups (probably elementary school or middle school aged and onward).

(For those that know me personally, I'm very willing to set folks up with a login shell to play Angband, Zork, Nethack, etc. It works best if each person has their own login.)
