So we are hating the "cartoony" comments. Why? there is cartoony textures, lighting and colors...... that's true. And Cormacolindor post is evidence, since he is arguing that "colors are good, like oblivion", are they?
The Cartoony look of some parts of the game, not the entire game are true. Saying the game is cartoony maybe isn't correct. Saying the game is photorealistic is more close to what it is and looks like. But i'm not a fanatic that only sees the good and deny any criticism. I shared a point of view with Reptile mod about some color grading and sharpening effect used in old shots and maybe new ones, this is what is happening, some colors looks more saturated, some people would like that more than dark and brown colors.
In my opinion, it's not just some colors but some lighting is different and textures in vegetation. This could be a lack of post process filter that make the game more sharp and dark like a Sweet FX effect, or some changes in lighting.
Anyway, the game looks mostly Outstanding, near photorealism in some places, not that much in others. Colors are too saturated and washed for my taste.
