Not sure, curious why you'd like to know?
Thinking that some people may need to forward the ports. I have no clue how networking works even in the slightest detail, so hats off to you for doing some Codey Blaine. Are you the only one coding? Even with a few more people that's still quite impressive. Let alone one, overall coded good, and in terms of atmosphere you articulated. Doing great with the progress!
Just learned that there are 3 data centers for Unity's matchmaking: US, EU, and AP. It just shows you the games for the closest one. But, in the next build I'm going to add a workaround that lets you choose your data center. Eventually this will probably use something like Steamworks...
Yeah it's just me coding this shizz.
