PC also has problems. Truth be told it’s all about the kinds of games you play.

You can port forward of course, but you have to know which ports and obviously it only goes to one static IP

I can't say for sure, but I have never ever seen a PC game using UPnP. That said, I have only ever seen it once with a console, a PS3 in this case.

And, don't quote me on this, but most PC games are not Peer-To-Peer. They often come with their own server software.

Yeah, which pretty much requires you to do manual port forwarding. And if you're behind a CGNAT, you can't host.
