I know Satoshi will join me in wanting a Hyperdimension Neptunia dating sim, albeit for completely different reasons.
Personally, I'd love to see what the localisation team would do with the dialogue for that, the CPUs all have personality types that are perfect for a dating sim, and I can imagine the entire thing being painfully hilarious, because it would be so unlike a dating sim it'd be more fun to play as a result. Neptune's tendency to break the fourth wall would result in some very meta comments (her stuff in PP was gold, this would be even better), Nepgear would be shocked that you picked her when everyone else is so much more interesting and would probably have the most normal routes (with an added Vert route, because it was bound to happen), Uni would be all "but you're already dating me" (because of course this would be on the Vita), Noire would be a tsundere bitch whose perfect ending would be next to impossible to obtain, Blanc would just want her name in the credits (and it'd be there, too - anyone notice that in PP?) and you'd probably end up babysitting her sisters whilst she wrote her awful fanfiction, Ram and Rom would be excluded because that'd just be creepy, Vert would probably ignore you due to her FGO addiction or use you for advice on how to steal Nepgear and you'd just spend the entire game being hated on by Chika, and Plutia...ohhhh boy. I'd also want a secret Arfoire route, for shits and giggles. Plus some cameos and a whole lot of shiptease which would essentially ignore you as a player.
