Peer to peer for gaming was yesterday's issue. Today, linking multiple
players together is well solved and baked into the Steam library or
whatever is specific to the game's platform. Meanwhile, anti-cheat
measures require that the players be ignorant of each others' IP
addresses so that they don't compete by lagging their competitors with
a packet flood. Which used to happen a lot. There are still old titles
out there being actively enjoyed where you have to poke a hole through
the nat to play with each other, but as a broad concern NAT
obstruction of online games is rapidly fading away. The game
developers found themselves facing problems that couldn't be solved
with peer to peer even if the network made it easy.
