Favorite: page or not page?

I'm not very certain if I should make a Favorite page, or just insert favorite as a function in the users page. Let's take a look at what function I need for favorite:

1. Add a game to favorite - from any page
2. Delete a game from favorite <- from favorite view mode
3. View favorites of a user <- possibly from user page & favorite page

To view the favorite, I need to retrieve a list of mids with same userid:

SELECT mid FROM favorites WHERE userid = 'userid';

Then, with the list of mids, I can retrieve title, author, category from metadata:

SELECT title, author, category FROM metadata WHERE mid = 'mid';

then, print the result.
