First Korean guy was really impressed with our ghost brick based building system, that's really the only real detail to glean from the video. Which is good, because I'm sure everyone heard "Minecraft" a lot in his dialogue, and our building system is a large part of what sets us apart and what made him realized that he was in for a whole new shebang. And this one didn't take Korean to figure out, but he really liked the idea of jetting.
Second video was harder to make out because it was a bunch of guys on sub-par mics but there was nothing noteworthy as far as I could tell, just some guys goofing off on a silly server.
My Russki's comparably awful but that guy's actually fairly well known, and, uh, yeah, he sure does dig the server download times... Seemed to like the art style in Bushido's T+T weapons that were on the first server he played on, but understandably had some criticisms of vehicle handling until he started winning.
