I heard spirits are hard to do, but I'm wondering if they're isn't any tech to either simplyfy it or maybe go with cellshading.

There must be a happy medium where they can offer something more vibrant and drawn looking with the ease of development and ability to add costumes etc.

Whoever said life to be like a box of chocolates clearly didn't know what he was talking about. 

Life is more like a game of bumper cars. At every turn there is a possibility you will get screwed.
