My wife and I have a Wii and Xbox 360/kinect we are looking to trade in at gamestop along with about 20 or so games. I'd like to pick up a PS4 and Last of Us.
One of the things that I think is really appealing is the whole playstation network thing where I can download older PS1 and PS2 games, and stream PS3 games. So, how does this work? For instance if I go to the PS website and search for final fantasy, FF:IX shows up with "buy download." How do I know if that would work for a PS4 or not? I can't seem to find out if one "download" works across all systems or not?
The nintendo website is actually significantly easier to understand than the sony one in this aspect, because there it says which consoles can download the game. The FAQ for PS4 doesn't really contain this information.
Any advice would be appreciated.
