I found the game pretty interesting and fun, though it is admittedly quite easy. There is a lot to do, though; I've finished all the major tasks to date, and am still only about 66% of the way through the game. With that being said, it is rather disappointing to have the storyline completely finished before I've completed all minor tasks and classes as this doesn't exactly encourage me to want to finish them all.
What I loved about the game the most is that it wasn't extremely easy, but it was enough to make for super pleasant gameplay. I didn't get overly frustrated at any point and was able to complete the amusing storyline without walkthroughs or wishing for cheats. Just keep in mind that I enjoy video games more for amusement than actual hair-pulling challenges, so my enjoyment of the game may be more than yours.
