My fondest Firefall memories were long, speculating forum posts that hyped the game to oblivion before the real product arrived.
Oh, and I guess some game things too, mostly from beta:
1) Playing leash medic for Xenogenic during a Harvester match I think, we were pretty unstoppable. And then leash medics went bye-bye. Outside of that, he and I mostly just talked about rum because I'd sent Red 5 some Kraken during Booze for Beta.
2) Out-sniping Souperior in TDM. Once. I saved that screen somewhere but I have no idea where it ended up. I felt like I was good at sniping for once, only to be proven wrong every other time I tried.
3) Somehow managing to sneak into some rounds of Harvester with Wil Wheaton and Nathan Fillion for Firefall Fest. And then when I'd try to direct traffic in text chat, James would read out what I typed and announced it on the stream which I have to think did not help our chances. (We got splatted hard.)
