Ctrl-f: Nier...
You're slipping Gaf, I'm disappointed.
But yeah, apart from some already mentioned games, like Red Dead Redemption, God Hand, Skies of Arcadia and Super Mario Sunshine, one of my biggest requests would be Nier. Not only would it hopefully lead to a more smoothly running game with less technical niggles, but it would also allow more people to get into the series now that Automata is on the way (which is especially nice now that that game has many links to the first one it seems). And just like with Bayonetta 1 + 2 on Wii U, it would be nice to have both Nier games on the same current gen systems.
More out of left field for me would be Grandia 1, the Shadow Hearts series, Vandal Hearts 1 + 2, Seiken Densetsu 2 + 3 (localised in 3's case and with online co-op for both) and anything from Panzer Dragoon (so I can finally catch up with that elusive series); maybe not full remasters if that's too much work but at least touched-up re-releases.
Edit: I'd also take a new version of SFIII Third Strike as always, especially if we could choose the old version and a new version that attempts to rebalance the game and that perhaps even adds a handful of new characters (Juri, Sagat?).
