Boy I couldn't disagree more re mega man 7.
It's such a cheesedick image. Mega Moobs. I never much cared for US box art that at least kind of tried to look like the Japanese art. To that end, the Mega Man 2 art is better from a design standpoint than Mega Man 3 starring Whoopi Goldberg—sure, Mega Man doesn't have a gun and he's not six feet tall, but at least it's a cool image. The alternative usually looks like bad '90s Disney VHS art: an approximation of the movie art but something's off, be it proportions, facial features, whatever.
If you're the type who doesn't care for manga-style illustrations, I can understand not really digging the Japanese Rockman art, but that stuff always looked great—nicely drawn, well designed.
By the way, I've never seen this ad before:
Shame it's so badly covered up by game screenshots but that's a pretty darn funny ad. I wonder if anyone's got the original piece?
