Otogi is a Sega property.

I'd say bring back Magatama, which a hack' slash and  MS property. 

Check it out.

If Phil could show something for Phantom Dust with the original creator (Yukio Futatsugi) now at helm.

• No incremental upgrade (unless it doesn't have exclusives and versions for the original Xbox One don't suffer technical issues).
• Actual gameplay of ReCore, possible release information.
• Release information for Cuphead, limited retail release like Ori and the Blind Forest.
• New gameplay of Scalebound.
• Gameplay and release information for Crackdown 3.
• Gameplay and release information for Inside.

• Information on future Xbox One firmware, including full offline mode (with local accounts).
• I'd prefer it to be multiplat, but Beyond Good & Evil 2 being saved by Microsoft (really anyone) would be great.
