The fact that developers have to cater to multiple platforms that have hardware limitations and different operating systems has led to worse quality of games of time. Console exclusives are anti-competitive, monopolistic, and they lead to a terrible consumer experience.
It’s not like if consoles stopped existing then developers would solely target top-end PCs. They will target as large an audience as they can, unless paid to stay exclusive. Most games these days use a pre-made engine that already targets multiple platforms, so it’s not as difficult to port to multiple platforms as before.
