UV Maps

If I understand right, games in blender run better/faster if the materials are UV mapped. What about ‘toon’ colors, would you UV map those as well? Thanks for any help.

I guess that you have never used UV maps before?
Here it is explained:

And i`m not sure how well games run with or without UV maps, but i know that texturing is not possible without UV coordinates of the object, so if you use textures in your project, you must make a UV map of objects. If you use toon shading without textures, UV maps are not necessary.
