Meh -
I can see why RPG fanboys are all over this and I can appreciate that it took a long time to complete. I especially can understand how this works as a Japanese project for school. However, it's clearly not original, except in story and therefore I can't really give it full marks. It's satire, which is the easiest form of comedy and these days, rarely funny (ergo SNL).
The author is definitely talented and I'd like to see him create original material. That will be the true test.
