what would be awesome is that they purposely left alot of the narrative out... as in, if the Guardians really are part of under a spell/hypnotized, a generic/boring story is behind it, but they don't question it because they just need one tinhy little reason to do what they are told...
I would love to hear back on this as well. I bought the digital guardian edition for the PS4 and was going to eventually get it retail on PS3. So if I can play it backwards for free that would save me some money and make me very happy! =D
Just to be clear, you have to purchase a digital copy on last gen to receive the free upgrade. Hard copies from physical retailers like Gamestop and Amazon will not get upgrades.
