I am a PhD student from Taiwan, and am working on a study on game scoring system.
My study will begin from finding out the functions of the scoring system in order to make a taxonomy of scoring system.
Here are the functions I currently found in two different perspective - game designer's perspective and player's perspective.
I will be glad if anyone can figure out any other functions that I might missed.
Also, if the following explanations are not clear enough, please let me know as well. Thank you!
