Sony & Xbox once used to have exclusives for their platforms. Xbox opened up completely and releases everything to PC as well. Sony opened up later and now brings their games to PC as well. Sometimes a year later, sometimes a month. So they're multi Plattform now and you can choose where and how to play it.

EA and Ubisoft decided to open up their LAUNCHERS and give you the choice where to buy& play - it's not completely open, because often you'll still need their browsers but it's a step in the right direction.

So the trend seems to be to open up more to reach more people and sell more games that way.

EPIC on the other hand is completely closed, buying exclusives for their launcher or for a certain time. It's a shitty approach to force people to their store and they still aren't profitable - that's the only good thing about epic proofing that this approach doesn't work anymore.

Are Sony/Xbox/EA/Ubisoft perfect? No. - but they all get that being more open is the way to go. They don't do it because they're nice or want us to be happy with games - They do it because it's profitable, but coincidentally that's a good trend that's worthy of support.
