In no particular order but can always get excited by whatever those guys are releasing.
Honorable Mention:
I don't care what anyone says about Rareware nowadays, still one of my favorite companies out there and Sea of Thieves is some of their best work. Not only that, but a lot of their games under Xbox are some of the best, Nuts n Bolts was most certainly ahead of it's time, Viva Pinata games are some of the most fun and chilled moments I've had with a Rareware game, Kameo was an amazing game and lots of fun to play. The only game I will say that was meh, under Xbox, was Perfect Dark Zero.
