late response, and partially, what drac's video says.
game itself is weird.
camera can get clumsy at times, and goes to hell once you actually managed to lock-target an enemy.... not to mention, targeting stuff is awkward and clumsy, so it is better to just swing wildly to hit stuff.
while it isn't much of a problem on melee classes, kills and stuff is determined by a button sequence, which greatly affect gameplay on a mage class or archer. special abilities are all there from the start to the game, only thing that affects their scaling is the weapons or gear.
difficulty curve is rather steep, playing online with people seems to be the best option to clear some missions because boss fights can get ridiculous hard, especially when you have to defeat a "certain" part of the boss to weaken it, or get a rare drop.
trailers made the game look awesome and makes it look great.. which is not.
Phantasy Star Online (and similar) makes this kind of gameplay much better.
