The absolute worst thing about this game is the combat chatter. Not only is it boring and repetitive, but it turns the entire party into a bunch of sociopaths who treat life-and-death combat like it's some sort of sporting event. It's never a good thing if the characters you most want to kill in the game are your own party members. Luckily the combat chatter can be turned off by turning the voice volume all the way down to zero.
Aside from that, it's a mostly OK combat-heavy rpg with a bunch of terrible design decisions. For example, you don't learn skills, you temporarily gain access to them by using equipment that has the skill attached. This means that the only real difference between your party members is how you distribute their attributes. It also means that you can only have three skills in your skill bar at any one time. And you're totally at the mercy of the random number god for getting the skills you want.
Other pet peeves include level-and-stat-restricted equipment, way too many equipment drops, way too much combat, annoying difficulty spikes at the boss fights which require level grinding to bypass, and half of the books in the goblin library would have to have been written after the goblins took over, which makes no sense continuity-wise. I can tolerate most of these flaws in a Diablo-like where the combat is actually fun and exciting, but not in a party-based pause-to-give-orders wait-while-the-party-fights game.
The absolute best things about this game is the various lore books. The game would actually be improved by publishing the lore books as an actual book and throwing the rest of the game away.
