How could you hate ADOM?
It's too hard and also pretty dull as a game.
I disagree completely with this statement, but to each their own.
I like Adom because you tend to find very unique and powerful weapons more often than in Angband (I do love Angband as well though), etc.
I also like the spells in Adom better than in any other roguelike.
There are features to Adom that I dislike though, as there are in every game, so I can't assume everyone is going to like it as much as myself. It was also the first roguelike I ever played.
