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.
Most developers counter that they do console exclusives because there’s too much piracy on the PC gaming market.
No idea if that’s true, or if it even matters.
Personally I think the quality of games has suffered mostly through pressure from investors (and fans) to release them as early as possible, and focus is now overwhelmingly on multiplayer online experiences rather than carefully curated level and mission design.
