My idea is that when you go to your game history tab, you have the option to change the way you games are presented to you. Instead of showing in chronological order, they appear in franchises.
Example. When I click my game history. Different groups will appear, each group will contain their first game and then, all their follow-up sequels.
Other feature i have in mind is that you can name the franchise as however you like.
Hope you see this! New update is awesome
