With gamepass coming to switch this would be a no brainer.

I have played them there. This isn't about me.

I don't "want" them on Switch, I wouldn't even buy them if they did come, I'm just saying it would be a mutually beneficial move for both parties. You're totally free to want Mario Odyssey on your PS4, but it's almost certainly not going to happen because that wouldn't be a mutually beneficial arrangement.

MS isn't just in the business of MS gamers (Xbox and Windows) per se.

Here is the flaw in your argument, you think MS gamers lose because MS supports other platforms. Its the opposite, MS would invest more in games if their revenue increased. Risky projects are easier to justify if they can make money elsewhere.

Hypothetically, lets say MS has rejected the idea to make a new Banjo Kazooie because its not financially viable on Xbox. But what if MS hedge their bet by supporting Xbox, PC and Switch? MS gamers would benefit because they would get the game that might not happen otherwise.

Another possibility is maybe MS could get some exclusive content from Nintendo, like Bayonetta 2 and 3. Unlikely, but more likely than an actual Nintendo IP.

But wouldn't benefit in the least MS gamers, just Nintendo gamers, which is what we are claiming and that it makes MS inferiorize its players since it is giving but not receiving.

And from what we heard so far they didn't get anything from Nintendo so far. And considering that Nintendo is the least likely platform to buy big games not from Nintendo, them the money benefit that would supposedly make more games to Xbox is just a "what if". We hear year in and year out that MS have money to buy the win on this or next gen, and that Xbox is profiting greatly so not sure why this tidbit money would make all the difference (they already port games to PC for the whole of 8th gen, so no new revenue stream).

Ok, let me see if I understand this: MS investing time, money and manpower to port a game to Switch instead of using those resources to, you know, develop their own games, would be beneficial to them...

And then we look at the best selling games on the Switch and find out the best selling 3rd party game (that doesnt have Mario on it) is not even close to the sales of frigging 1, 2 Switch...

Yeah, that makes sense.

And don't forget it hugely favors the MS gamers.

Mario Odyssey came out in 2017 and is still selling well.  Halo Combat Evolved came out in 2001 and is not a seller anymore.  Don't you think the comparison is a bit silly?  

Porting Combat Evolved can't possibly take many resources from MS.  I don't think it will ever happen, but I don't see how porting a classic game is a problem.  When Banjo Kazooie hit the Xbox 360, where N64 fans really upset?  

I questioned about porting Mario Galaxy or even older games to Scarlet and he was also against because it would be bad for Nintendo, even though it seems that even porting of Halo Collection would be a fantastic idea for MS and for the owners of X1.

Nintendo porting older games would not hurt. Nobody is buying a switch for Mario sunshine.

That would at least make the request equivalent.

Also would you like if Nintendo started putting the WiiU games on X1 and/or PS4 without getting a single game from those systems on its own due to the trade?
