People have been crying about no PS5 games since It's launch, so It's nothing new.
(Even though It has more games than PS4 had for it's first 4 years. PS5 just lacks THE game, like Killzone 2, Uncharted 2, Uncharted 4, Halo 2, that made people rush to get the new console)
PS5 has tons of games, but the problem lies in the small announcment windows inbetween SIE releases. They could have revealed Astrobot last year If they wanted to. Add the billions of PC ports to that, and It just feels dire.
Xbox death resulted in the switch of Sony's view on exclusivity and PS Studios games.
Normally, exclusive games were never supposed to be proftable. The idea was to make a huge library of interesting and diverse games, to drive players towards your console. Sadly, the death of competition changed that. Sony no longer has to make you buy a console. Those who play new games on consoles will buy the PlayStation anyways, so why bother right? It's not like they are going to buy a Switch to play 720p/20fps ports of PS3 games.
So now SIE has no excuse to not push towards being profitable. Especially since the costs keep rising, and the PlayStation playerbase doesnt seem to be all that passionate and supportive towards PlayStation's new releases. (60m consoles sold, and only a milion copies of Ronin and stellar blade has been sold. While not terrible, when you compare that to the Switch where Nintendo can just randomly bring back a no name IP like Pikmin and It tends to sell over 5m copies, It just looks pretty bad. Most of the PlayStation playerbase are casuals who play CoD, Fifa and fortnite. The hardcore passionate fanbase is no more than like 5m users)
