Hmm for a quick review I'd say it's a good solid old style mmo. Tab targeting (with defensive), simple gear that doesn't need half your screen to display, low fantasy.
Slow leveling, real darkness, dangerous enemies. Good group combinations but you don't necessarily need specific classes. Can usually grab a tank, healer, damage and fill the rest with whatever.
The deeper you go in a dungeon the scarier it gets because you realize there's no way you'll be able to get back to your stuff alone if you die.
