After what were undoubtedly constant requests from fans — referenced directly by Satoru Iwata — Nintendo has unleashed new Mario Kart 8 Nintendo Direct broadcasts to reveal more about the upcoming Wii U blockbuster. Though regional variations were generally minor, there were subtle differences such as a free game promotion for those that pick up the racer.

In both Europe and North America you have until 31st July to register your copy of Mario Kart 8 on Club Nintendo, including codes with standard and limited editions, as well as console bundles and copies bought directly from the eShop; in return you'll receive a free download code for a retail title. In Europe you'll have a choice of 10 games, while in North America the list includes four titles; below are the choices that Mario Kart 8 early adopters will have.

Combined with upcoming Mario Kart 8 hardware bundles, the offer of a free game could certainly tempt new adopters; for existing Wii U owners, meanwhile, this seems like a good chance to boost that game collection.

Are you planning to pick up Mario Kart 8, and if so which free game will you claim?
