ADOM is better in a way coz it has a stronger storyline and u keep getting quests from NPC's
it has multicolor gfx
but there r too manychoices to make in it like what to upgrade
75%times i dies were coz of lack of food or dying in 2 minutes after being hounded by wolves in the forest
nethack is a more rounded game....its opensource so spoilers r easy to find/make...ADOM isnt
best till now: lvl9 human monk in lvl9 dungeon...killed by a lizard while paralysed by floting eye
