Currys/PC World is breaking in gaming deals this year with a £10 reduction on both the Mario and Luigi versions of Mario Kart Live: Home Circuit. The AR racing game for the Nintendo Switch is basically a fascinating mix of video game and RC toy, in which players lay out a physical course in their own home. Then they can drive a remote control kart through the course via their Switch, seeing an enhanced AR version of the game through a camera on the kart itself.
Our own review of Home Circuit can be found here, and though we had some troubles, it was ultimately a good experience, and many of the kinks should be less problematic if you have a good amount of floor space to work with. Below we've listed the two main versions of the game - one with a playable Mario, and one with a playable (clearly superior) Luigi.
Both versions have since sold out at Currys, but the Luigi edition is available for the same price at Amazon
