Or you can just make a credits mode, where the game skips directly to the end credits so you don't have to put in any effort at all. I think what you're looking for, is a book. But then, that'd require reading...hmm, that's difficult for some. So maybe a book with footnotes? I mean, it still requires reading, but it gives you the gist of it.
Nah man, too much effort. I would like to put forward the "Participation Sticker", in which paying the price for Bloodborne lands you a sticker that reads "I beat Bloodborne"
But then you have to go through the trouble of cleaning off the sticker gunk after it gets too old. They should probably offer a free cleaning assistant to come and take care of the mess, also.
No, that is an outrageous proposition. What we need, is a LAWSUIT (!)
