How many games thank the player at the end of the credits, whether through a name you entered or just a generic "and you" type of thing? I'm pretty sure more than enough to warrant a page on the wiki. But should it be a person page (credits) or a concept page?
"You" isn't a specific person, but a broad group. It certainly shouldn't be a person page for that reason - it's not a person. Developers regularly list their pets in end credits (Telltale do this all the time) and they don't get person pages because they're not people, they're animals.
As for a concept page, it seems a bit broad and general and I don't know if it would be of any use.
There are some pretty good reasons why it shouldn't be a Person page and I agree with MattyFTM on why it shouldn't be a concept page. A list is really all that is required to fill this need but unfortunately I don't think anyone but the list creator could edit the list.
I think it works as a concept page. "Games that thank the player"
While the usefulness is questionable, I don't see how this is any less viable than some of our other concepts.
Pretty much this.
Just wanna add that I too think this could work as a concept page.
