We already discussed this. The Playstation Plus subscription isnt paying for internet Multiplayer infrastructure.
It is. The party system, voice chat services, and the ability to join on or invite friends in a universal way regardless of the game without having to make an account for that game all requires expensive infrastructure and manpower to build and maintain.
Oh I was... So Xbox game pass released in 2002, PlayStation followed much later in 2010.
Xbox GamePass released in 2017 and has nothing to do with multiplayer. The multiplayer service Xbox live released in 2002 and PlayStation followed in 2006. You’re not beating the allegations.
the subscription "fee" isn't what fixed multiplayer design, that was fixed by... Game developers.
Game developers were uninvolved in the fix for multiplayer design. Game developers are unsurprisingly, only involved in the development of their game. The reliable third party social systems were designed by engineers at Xbox and Sony, and on the PC side at Valve. Multiplayer existed on consoles prior to Xbox Live and PlayStation Network, but just like their PC counterpart, it was clunky, unintuitive, and inconsistent between games. The PlayStation network and XBL were created as a direct result of those issues.
