This isn’t Daver Rickey ;p
Just a scheme I want to save. Perhaps I’ll write something about it in the future:

| Surprise | strong | weak | Wonder | 
| Mystery | medium | medium | Curiosity | 
| Suspense | weak | strong | Empathy | 
World of Warcraft seems to do well on the first line, that’s why some say that it won’t be a huge hit in the long run.
