I usually join the worst team because of people like Serafim and Yuliy, then I start recording. That team usually is NF.

I'll join the team that's losing every time. I try to get on the unstacked team if I'm playing at the start, but stacks follow me pretty hard, so it's often unavoidable, no matter how that may sound, because it is the truth. I get the biggest kick from joining teams who are on the verge of giving up, and doing a last ditch rush for them with an APC or something, and winning. Nothing beats that for me, nothing beats winning against all odds, and that adrenaline rush from pulling off what no-one expects to be possible. Moments like that are what I play Empires for.
