They did say they'd be back...
On topic: I've been playing this a bit recently and it's nice but I don't like how chance-dependent it is. All spells, attacks etc. have a % chance to work and outcomes are entirely binary (i.e. you either kill something or you don't, there's no hitpoints), which means that a run of bad luck can be absolutely catastrophic because there's no incremental success or failure to average out the vagaries of fortune. I never played the original Chaos so I don't know whether that's just in the spirit of the original, however.
