This trailer reminded me of a simpler time. A happier time.
When Capcom made games for the sake of making games and weren't trying to create the next big Hollywood blockbuster with every title they released. When they didn't alienate their own distinctive identity just to appeal to Western audiences, and instead created quirky, bright, colorful adventures with an elegant simplicity that has all but been lost.
(It's also probably all that remains of Mega Man Legends 3, so there's that, too.)
