Not to mention Sony already allowed cross play before on a MMORPG. ps2/ select ps3/360/pc. Its been done already. It was controlled by a separate service of everyone logging into playonline.
Mind you I had many moments of PERSONALLY attacking players verbally on an alt account on 360 and ps3 and ps2. Someone on a ps3 reported me while I was on xbox. This someone was a friend and xbox couldnt do anything. It happened IN GAME and had to be taken care of with Play online.
I read an article earlier about it. Technically speaking..If someone was harassing one person from a different console. IT COULD cause issues are solving said harassment.
Also, When SE wanted to do FFXIV cross play with xbox. xbox said no because they wanted exclusive xbox server so said players couldnt play together anyway.
I mean I see everything going full circle here.
As someone who owns both consoles though. I would DREAD playing with people on xbox. I only play xbox with friends. Everyone else is just so damn toxic compared to PC and sony.
Having people scream into my mic about how they make my mother gargle that shit over and over and over is an almost everyday occurrence on xbox.
at the end of the day though... idc PC players would destroy consoles players. I have everything. PC player will always have the utmost advantage in tech if both were equally skilled.
