Not bad: not really a grind, some good backstory, they actually created new maps, and the last battle came perilously close to being a Total Party Kill. Any combat where I have to run around for a while being chased by the bad guy until my spells regenerate enough to bring my party back to life is pretty much by definition a challenging combat: the designers expected me to be a Leroy Jenkins*, and lo! I was. If I wasn’t a mage with group healing/resurrect, I’d have been hosed, hosed, hosed.
*You know who Leroy Jenkins is.
