Its fun for a quickie sort of coffee-break game. But it lacks a lot of depth that most roguelikes have. And it is far easier to simply insta-die to events.
Oh, you found a hostile survivor with a shotgun. Congrats, you die!
Oh, a zombie master, he has more zombies than you can fight, and this zone doesn't have connecting zone borders, you die!
Oh, a bunch of bikers spawns on you, you die!
Your safehouse door comes under attack by a zombie. He is too tough to fight and there are too many to run from, you die!
Not once have I had a nethack/angband experience where I feel that my own stupidity caused my death. Every time it was "well, that random number generator just killed me". And that really is a shame, part of the appeal of a zombie apocalypse is that you feel like you are the reason for your own survival/failure. I think Fort Zombie hits this feeling much better.
