This is a thread I want to dedicate to all the games that should be multiplayer (at least 2 players) but sadly are not... so any games you feel should be multiplayer post them! "Devil Kings", it's a great game, but it should have been 2 player split-screen, as it does follow in the footsteps of "Dynasty Warriors", which implemented this very option!
Yakuza Of The End another great game, but with all it's characters, it would have worked well as a 2 player split-screen co-op, something along the lines of RE: 5 as it is a zombie type game, this time around!
Cool. ^^ I have downloaded and a friend of mine was playing and he said he quite like it as well. My verdict to this last Yakuza is nice and indeed more like Resident Evil VS what Yakuza game as usual JPN GTA style gameplay.
Star Ocean: Til The End Of Time, this game could've really used at least 2 players in game, as battles are fought in real time and some of the bonus bosses are extremely difficult fighting them alone. It could've played like "Tales Of The Abyss"!
