I said to myself that I'll watch a little bit not the whole the whole thing, but I ended up watching the whole thing T_T. Wasn't bad, I want some eggnog with rum now..
Wow... That is so cool.

I've been to that arcade. It's so much more amazing in person although the video does do a good job capturing the essence of it. Also, that was just one arcade. There are over 20 more in Akihabara alone.
