Nintendo turned on the nitros with the new Wii U bundle for Mario Kart 8, not forgetting how every copy of the racer bundles in a code for a free game. Good thing, then, MK8 itself is a 4.5 stars winner according to Joystiq's Thomas Schulenberg. From his review:
"Despite an unfortunate change to its battle mode, MK8 is a solid extra lap on a series with a great foundation. The gravity-shifting sections spliced into existing and new tracks feel like a natural extension of the series rather than a gameplay-changing revelation, but it's a strong complement to an already enjoyable experience. The social features are surprisingly solid and may even outlive the total course selection, but it helps that the new tracks feel as worthy of a revisit as the series' standouts."
