So I played and finished Kingdom Hearts Final Mix in the Kingdom Hearts HD 1.5 + 2.5 ReMIX compilation for the Xbox One. Yes, the rest of the Kingdom Hearts games released back in February and I didn't even know about it. I didn't even play the ReMind DLC for Kingdom Hearts 3 yet. I don't think there's a physical release for Kingdom Hearts HD 1.5 + 2.5 ReMIX & HD 2.8 Final Chapter Prologue, so I bought them digitally from the Xbox store.
Play together with Xbox Live Gold. June's 2017 Games with Gold lineup for Xbox One includes: Speedrunners and Watch Dogs. Bonus DLC for Phantom Dust on Xbox One as well. For Xbox 360 owners (and through Xbox One backward compatibility), June kicks off with Assassin's Creed III, followed by Dragon Age: Origins. June's lineup provides over $94 dollars in value and up to 4000 gamerscore.
