I think celshading is nice.However, I dont know if it would make gmes like fighters look better. LEt's keep in mind, this is justa way of rendering after all, so these things are modelled like they use to be, just rendered differently. I mean, the3D models will be as lifeless and simple as they used to be. However, this new rendering method adds a bit of life to them.Things like faces etc. still look like poopy IMO.
It's a new fashion. Like somebody in Gamefan said: "Cel shading is the lensflare of the 2000s"
as long as it's not abused, i think it's OK
