anyway to make the game look a little like a cartoonist look. Not all the way just a touch.

Probably this thread gives you some ideas how you can create something like a cartoon shader: https://forums.unrealengine/showthread.php?306-trying-to-make-Toon-Shader-Material-on-UE4 
What do you mean? Outlines? Cell shaded? or hand painted textures stylized to look like comic books?
