That's what I thought. Thanks. But what exactly would the rules of engagement be? What if a company wanted to host a game on its own servers (independent of psn and xbl)?
If Microsoft plays nice, the ROE may be just be a set of networking API with some encryption. ( i guess that is what sony and nintendo have at the moment for FFXI SFV)
If Microsoft wants to be aggressive and demands the full azure server stack integration, then it is easy to see the PR war becomes inevitable.
Also i like to argue that Sony actually benefits more than MS from cross network play
if and only if Sony deemed the rules of engagement is fair to all parties.
Check out the xb1 vs ps4 usage thread on gaf, you will see a lot of gamers citing 3 main reasons for choosing xb1 over ps4: exclusive, controller and friends circle.
Cross network play remove the friends circle argument and suddenly there is one less reason to purchase a xb1.
Although one could argue ps4 also suffers from the same effect, I have a feeling that XB1 suffers much worse.
This is because the games become a much more important factor in choosing which console to buy.
1) Multi platform games still seems to always run better on ps4.
2) Sony 1st and 2nd party output is going strong while MS seems to grow weaker. ( halo 5, titanfall, tomb raider)
3) Japanese companies support on ps4 is a night and day comparison to Xb1
4) PS4 has a better reputation for catering less popular genre and have a larger indie scene.
Yes this is all my personal opinion but i think the public and gaming press is something similar to this. So average joe is more likely than ever to pick PS4 than XB1 if he doesnt have to care about his friends console choice.
Long term, if we looked back to PS3 and XB360, one of the reasons why PS3 cannot compete with 360 is because of the gamers circle lockin effect.
Sony always have been the popular gaming console brand and it relies on it to survivr the ps3 era.
Removing the lockin effect now means in the future it is easier for sony to recover from ps3 quesa disaster.
My 2 cents anyway. Peace
