Destiny having a shared list does make sense from the perspective that it's cross-play between PS3 and PS4. Shared lists are not as uncommon as you'd think. A lot of the cross-buy share across all three systems. Swapper for example has one list for all three systems. Same with Hohokum, Race the Sun, Rogue Legacy, Spelunky, and Titan Attacks!. Tons more share PS4/PSV trophies. Games sharing PS3/PS4 trophies but not PSV are more rare, mostly because PS3/PS4 cross-buy isn't that common.
I don't really care much about FF7 either. Cloud always kinda felt like a Chrono ripoff to me, and Sephiroth is a shitty villain since he's really nothing more than a dude with mommy issues who went nutso. The world never drew me in much, either. I played right to the end of FF7 and just cared so little about it that I never got around to beating the game.
Honestly I'd rather see them release a port of FFXII.
