Plaything though this at the moment and its well worth a look, great storyline, good graphics, good gameplay. Its only minor letdown is, you feel a little overpowered when taking on guards that makes encounters more of mere nuisance than any real challenge.
Having said this, the storyline keeps things interesting, and some of the acrobatics required to progress are a little challenging. The gameplay also makes it quite easy to while away hours just running through the streets killing theives in amusing ways, and causing havock with the city guards.
Overall this game is well worth a look, and by all accounts a huge improvement over the original (although I've never played the original myself).
