I had to read this OP twice, because it was a bit strange, it's really reaching tbh.......Playstation using MS's gamepass service? In which generation? That's not happening.....Sony is not going to use MS to fuel any part of their console diet.....
Also, OP must remember that PS NOW is the most successful streaming service right now and you don't lose access to games, the list just keeps on building....and of course you don't need PLUS to play online....PS-PLUS is also the most successful online service right now, still offering the best monthly games,
and yet, you don't need it to play fortnite and FREE TO PLAY games or even betas.....Which brings us to the PSN store, which is the most successful store right now due to frequent sales, pre-loading, decent storage sizes on exclusives, quality exclusives including the VR channel, so of course it's going to be pulling the most revenue.........So it's like this, why would Sony leave successful services, which covers a wide range of customers to chase a cash strapped service that depends on millions and even billions of subs which MS just cannot muster.......That's why MS is giving gamepass for free literally, 3 months for 10 etc.....and they don't have the content to push such a service anyway, so yes, they can buy a boatload of sub-tier devs, but that won't change the dynamic and attractiveness of the service for mass market appeal, you need a bevy of great games to attract folk across many devices....
So no gaming company is sitting their twiddling it's thumbs saying, "boy, PS5 will be hooked up to gamepass for all that great content"...Hell, everybody and their grandma's seems to be setting up an online store atm......No one is giving into MS gamepass as the onestop gaming plug-in, everybody is looking to establish their own and pull their own installbase and customers and in the end whoever has the best content will win, nothing changes in the gaming space. Some services will rise and fall, but I think Sony will stand tall when all is said and done with no dependency on MS..........That's for sure...
Also we must stop projecting gamepass as this super successful service that it's not, where every platform provider is just sallivating to give MS that cut.....MS can't even muster 20% of it's base to gamepass and they've been giving the service literally for free.....Yes, persons will take the trials and 50% gamepass deals and sub in the months where there is a game they want to play, but what is the point of subbing year round? Games leave the service and the games on there are not exactly the holy grail or require consistent subbing, besides, you still have to pay for live when on gamepass.......Which shows MS is losing money, it's not as gravy as they say........So many people who were going to buy Horizon at retail did not because, "hey" free subs, 3 months for $10 et al.......So much revenue lost to build a service that depends on content, which MS has been sorely lacking this entire gen.......So what will cause people to actively sustain their gamepass accounts, what content? I know persons who were going to buy Horizon but instead chipped in for a gamepass sub and now share access to these games across many friends, that's less people buying these games........And don't talk about "they just want your sub and persons into the eco-system" because that can easily be boosted by sharing and don't be fooled into thinking that a tonne of persons are playing into MS's DLC and monetization in these gamepass games, whether that be playing online or actively playing SP beyond the mating period.......SOT, SOD2, Gears, Horizon are not generating the revenue MS needs to make back on a game sold at retail for $60, many persons just try the gamepass games and leave it at, gamepass is not big enough to rely on a huge payday from DLC or monetization, not even close......
Something like gamepass may be successful in the future, but only when all device markets are penetrated with great content, gamepass is not close to being that in it's current state...
