If any company is currently the leading light in prioritising enjoyable gameplay over pushing technology it's Nintendo. A look at the current and upcoming sleight of games re-affirms that clever ideas, established gameplay and colourful visuals are the priority - in most cases - above pushing boundaries.

Of course, that's not always the case, and Nintendo has in the past stretched its hardware to achieve improbable results. That seems to be the intention with this apparent prototype - if it's real - which is a simple experiment in a different camera angle and 3D visuals to push the Game Boy Advance to its limits. Mario Kart XXL - a limited build supposedly brought together by Similis - showcases dual mode-7 layering; it may look slightly messy and not particularly fun to play, but on a technical level was certainly impressive for the Game Boy Advance.

It's intriguing to see, though we're not surprised that Nintendo has stuck with its traditional approach to Mario Kart. Just because you can do something, doesn't mean it's a good idea.
