ADOM is one of the major 2nd gen rogue-likes (including NH and Angband in this group), and they're similar. I played ADOM first, so for me NH required re-training; so I may be biased. ADOM offers a more complex world with different endings, compared with NH that AFAIK focus on the Amulet of Yendor only (I might be wrong on this!).
