Last year's reveal of New Super Mario Bros. Mii underwhelmed some last year, but this year's screenshots of New Super Mario Bros. U look a lot better. We've put together a gallery comparing screenshots from last year's technical demonstration to this year's game.

The overriding impression we get is that the backgrounds have been most visibly improved, but character models also appear a little sharper and less 'jaggy' than last year. We're not going to say it's the most beautiful Wii U game we've seen so far — our gallery of gorgeous Wii U screenshots should emphasise that — but it looks like it still has some sharp and shiny visuals to share.
