These are all I can think of that I own/owned so there'll be more to follow soon.
Question: Can I add PSN downloads and other downloaded games from the PS3 (i.e. PS1 classics from the PS Store)? If so, should I give them their own category or add them to the PS3 list or add the PS1 classics to the PS1 list?
