This is not the case at all.
Sea of Thieves a open world MMO game
State of Decay a open world survival game
Cuphead. Unique looking platformer
Tacoma. Exploration game
Halo Wars 2. A freakin RTS on console
Then we have Crackdown and Forza wich are indeed a shooter and a racing game.
Definitely a good list of games from different genres but here's the problem for me personally -
Sea of Thieves being an open world MMO first person game does nothing for me. I'm NOT an online gamer at all and this is where Microsoft focuses most on. Games that are online and are labeled as Games as a Service (GAAS) which I have no interest in. First person is also far less preferred than third person for me. If this game had an off-line single player campaign in which I could explore, fight, etc. by myself, this would easily be a pre-order and day one pickup even in first person but it's not and thus, my interest in it is non-existent. I will say this though - Sea of Thieves impressed me more at Microsoft's E3 press conference than any other exclusive they showed but it loses it's appeal because it's an online MMO.
State of Decay 2 is the ONLY game on the list that im buying and only because others here have confirmed that it can be played solo and off-line like the original game. If this changes, oh well. I enjoyed the original game on Xbox 360 and am looking forward to the sequel but the character models, animations in general and enemies all look exactly the same as what they did four years ago. Only the environments look vastly improved. Was also expecting it this October but nope. 2018 it is.
Cuphead looks good, real good but the plat-forming looks very generic. I think adding in all the plat-forming is going to backfire on this game. If it gets good impressions from those here who purchase the game and can be played solo (instead of co-op), I may buy it but as right now, nope.
Tacoma looks like one hell of a boring ass game period. And I know that PS4 has a bunch of the same boring ass games. Simply not for me.
Halo Wars 2 doesn't interest me simply because of the genre it is. No interest in RTS but it's cool that the console actually has one. Only problem is that at launch it was said to be almost broken in some ways. Don't know how true that is but either way, this genre doesn't interest me at all.
Crackdown 3 doesn't interest me whatsoever either especially since all of the destruction is ONLINE ONLY. Seriously? Three years later and I can't play solo with all of the destruction? Come on. Watching this game at E3, it basically not only disappointed me completely on so many levels, it was also a factor that eliminated me buying Scorpio day one. I'll stick with my Xbox One Slim.
Forza Motorsport 7 looks absolutely stunning but like GT Sport, I have no interest in simulation racing. I do love Forza Horizon 2/3 though and can't wait for FH4 next September.
I'm going to add Super Lucky's Tale as it's the only exclusive that im buying day one for Xbox One this entire year. Haven't played a single 2017 exclusive on Xbox One and while there have been an exclusive game here and there, the simple fact of the matter is that they don't appeal to me.
That's the number one difference for me - Sony exclusives are off-line single player story driven third person games that appeal to me in nearly every way. They simply "check off every box" where as Microsoft exclusives don't because their exclusives are the opposite of what appeals to me.
In conclusion, while that list isn't bad whatsoever and is actually pretty good in general, I think that for most who pass on Xbox One, prefer PS4 or both do so for the same reason as me - the games simply don't cater to what gamers are looking to play on Xbox One.
