For once the 2nd game is better than the 3rd.
Graphics - Very good. The BEST Cell shaded game to date. I love it. Maybe they are not real "graphics" but it is as "Cartoony" as it gets.
Gameplay - Very easy to learn and very good. Sometime it's annoying playing as bently but slys controls are smooth as ice.
Sound - The music is good when an enemy approaches and everything but I HATE the voice acting. Murray, you suck.
Value - Not much to unlock but there is the bottles again and pick pocketing gaurds for watches,combs, and more is very Satisfieing.
Final thoughts: You don't need to be a sly fan, but it would help.. A LOT.
