Instructions:

In the first column is a game, the second column is a franchise the game belongs to and then columns 3 moving forward are games in that series

Your job is to fill out the franchise for each game as well as all the games in that series. 

1) If a game has no sequels or other games in the series then you can leave franchises blank (but you'll see that for some of them its filled in)

2) You'll see that the first 12 rows are completed as an example

let me know if any questions.
