Here's a fun side-by-side comparison showing off just how spot-on the latest Super Smash Bros. recreates Mega Man's original NES incarnation. To quote Masahiro Sakurai, "maintaining his NES look was a top priority." I think they've done a solid job so far, wouldn't you agree? The resemblance is pretty striking.
You can see more side-by-sides over on the Seagulls and Shrooms Tumblr. Many thanks to Eric and Shin for the tip!
