What do you think about games with cel-shading like in Prince of Persia 2008 game?
I personally like the style 
But mostly I prefere realistic textures/materials ^^
I hate pretty much all cell shading, unless its a cartoon game and actually done well like Guilty Gear XRD. Most cell shading in games look bad, and artist tend to just plop it as a post process in the belief that it makes their art unique.
