On Zone in particular?
Met Noah (Yogurt/Yog) within the first few hours of playing seriously - not counting release day - trying to figure out how the hell Zone worked. He's a good guy, we were and have remained very close friends over the last 3-ish years; only hindered by my awful keeping-in-touch skills.
I recall meeting you, Alex, somewhat early - while playing events iirc.
Knew Kyle (fsh) from Era before Zone, we had some disagreements throughout our knowing each other. On good terms now and for a while; don't talk much anymore but have him added on Snapchat.
Was also cool with Chris (The Doctor) while he was still developing for Zone.
Some other friends were Mike18, Killua, Stratus, Aero, TritonFlow, Nobodypoor, etc. all of whom were in a group Google Hangout together (myself included) but no longer speak to each other. Occasionally talk to Nick (Stratus) and Lewis (Nobodypoor).
Also met Zach (Shmegg), Ken, Colin, etc. because of Zone, still talk to them. Great guys.
