What are some of the game series that you have all of the platinum trophies for? Others opinion may very but I'm considering a series to be two games or more. Basically more than one title in the series. Also if a game is a "spiritual successor" to and earlier game that counts as well. As for PSN titles not all have platinum trophies but if you have a 100% on one of those list it.
Alright. So to clarify a series:
Has at least two games in the family
psn 100% neither hurt nor hinder
Multiregional Platinums neither hurt note hinder
I personally don't have any but I one day hope to have the Platinums for both demons souls and dark souls as well as all five god of war titles.
