The only reason someone needs an open NAT is if they want to host the games themselves. It varies depending on the game because some games do a peer host. This is usually someone with the lowest latency connection. Everyone connects to this person to host the game. Gamers want to be this host because it gives them a few ms of advantage. Having an open nat does not affect their ability to play games. If they can’t host the games simply chooses someone else who can. When you have "Strict NAT" on the XBox, what it effectively means is that your XBox isn't able to open an arbitrary port on your NAT device and have it forwarded back to the XBox. If it can't do this, then it is never able to "host" any chat - all of its connections need to be made outbound. In cases like this everyone would need IPv6 because they would need to connect natively via IPv6, which isn’t going to happen for awhile.
Some other games connect to centralized servers. World of Warcraft (PC), Destiny (Xbox and Playation), and others use centralized servers for the game. This means the natting issue is irrelevant. Too much nat can adversely affect voice quality and other things, but only when it comes to hosting. Otherwise the chat is “Streamed” to whomever is hosting.
