Tough poll.
1. Recore: i think it has the most potential to be a great franchise for MS. It has great gameplay, likeable protagonist and its very different from Microsoft's other IP's.
2. Sunset Overdrive: I love that game! Insomniac is a very talented studio and xbox needs their unique and colorful games.
3. Quantum break: QB's story has a lot of potential but maybe they should rethink about the live action series.
4. Crimson Dragon: I havent played it yet but if the sequel is an rpg and it's anything like Panzer Dragoon Saga then i'm really interested in it.
5. D4: I would love a sequel but only if Swery is somehow involved in it.
i'm not including Ori because I'm sure it'll get a sequel. Screamride doesn't interest me and i haven't played Ryse yet.
