I don't mean to sound like a Japanophile or anything, but the commercials Capcom of Japan produces for the Rockman games are so much cooler than the ones we occasionally get in the west. I was always a big Mega Man fan, but if I'd seen these commercials as a kid they'd have made me doubly pumped for Mega Man! The following video contains commercials for Rockman through Rockman 7 (excluding 6). I think they've gotten around a bit by now, but they're still a lot of fun to watch.
