This 2DS comes bundled with Mario Kart 7 which is one of the best 3DS games and that has one of the highest replyability factor to it. Much like how many people only use their WiiUs now to play Mario Kart 8 and nothing else.
There are a range of game modes to try in solo mode, like Grand Prix and Battle Mode, but you can also play with friends or connect to the web to race up to eight people anywhere in the world. With eight cups in which to compete and 32 courses in total (including 16 you'll see for the first time in Mario Kart 7), there is lots to enjoy. There are even time trials to help you hone your skills – just pick a course, set the best time you can, and race against 'ghost karts' saved from previous record laps.
When it comes to choosing characters to represent you on the road, you'll find all your favourite classic drivers to pick from, and you can also let your very own Mii get behind the wheel! There are new characters to enjoy in Mario Kart 7 too, including Lakitu (the lightweight Koopa who usually counts down the start of the race) and Metal Mario, who is just as heavy as his appearance suggests, though his top speed is still incredibly impressive. Elsewhere, don't be fooled by the elegant Honey Queen, as she can hold her own on the track and won't be nudged off the track so easily!
Not only can you race registered friends, but you can also take on previous opponents and others you have met through StreetPass. You can set the rules of play and exchange data with other StreetPass and SpotPass opponents, exchange Mii characters automatically, and save things like player names, ghost data, and other community information.
