my opinion the vast majority of console gamers aren't switching to PC , and like phil said if they do thanks for playing ms games . i'm willing to bet we see allot of indie devs taking up crossplay very similar to the ps3 vita push .

It really is. Because it could either fail horribly or potentially give huge growth to Microsofts gaming division and I'll give some examples.

1. Bigger Game/Online communitys. The bigger the games community the bigger mindshare it has and the bigger replay value it brings. So this means more people buying dlc and micro-transactions and increase in word of mouth to grow sales (which is underestimated sometimes).

2. More hardware sales. Lets say someone owns an xbox, and that person is looking to buy a computer, they might have previously bought a mac but instead decide to buy a win 10 computer so he can download his xbox games. And vice versa, someone who has a gaming rig pc might want a console for the family living room, why not buy an xbox because a lot of his games will already be available for free? However this could backfire and pc gamers who want to pick up a console see no need to buy an xbox if they already get all its exclusives on pc.

3. Increase profit. Putting all their first party games on windows store will increase the number of people visiting the store. So for example, lets say someone goes to the store to buy forza horizon 3, they then see Recore and decide to buy that as well. So Microsoft just gained $40 extra profit from someone who was just visiting the store to buy forza. It isnt a question of will this happen, because it will, it's a matter of how many to really make a dent.

4. More games. Lets say Gears 4 sells an extra 1m copies because of pc sales. Microsoft now can use some of that extra profit to sign more exclusives and fund more games. Making their ecosystem even more attractive for consumers.

5. UWP Initiative. Microsoft plans to have uwp the standard for pc and xbox Which "supposedly decreases the amount of work required to port games between the two." So for example lets say a dev puts a uwp jrpg in steam. That dev then sees they can easily port their game to both win store and xbox one with very little development cost. Even if it only sells like 100k why wouldn't they target those two platforms if it costs them practically nothing?

6. Broader appeal. In some countries buying a console simple isn't worth it. However win10 is worldwide. So Microsoft Ips now have broader appeal, and all it takes it one of their pc games to blow up in countries like South Korea for huge profits.

We are all watching.
My guess on it has always been it helping win10 and hurting xbo sales.
No I don't see xbox gamers going pc....I see pc gamers staying pc or going pc/ps4 combo. Instead of a pc/xbo combo..pc is already a better xbo.
It shows that xbo failed as a exclusive gaming system. At the end of the day it's a win win for win 10.

Nice one

These declines are on the back of extra revenue received from releasing games like Forza horizon 5 on PlayStation. So I’m being sarcastic here when I said they should go back to exclusives. Killing off a revenue stream from Ps5 sales will only make things worse
