I will not accept entries from later versions. Mostly because future versions cut the number of laps down to 3, whereas Super Mario Kart uses 5. There are also a lot of changes and improvements from game to game, for example speed boosts from drifting around corners that are not present in Super Mario Kart.

I did wonder how long it would take someone to ask this though. I'm playing on the Wii U virtual console. There is a promotion going on just now that if you buy Super Mario kart on the eshop prior to buying Mario Kart 8 as a download, the price of the Mario Kart 8 is reduced by the value of Super Mario Kart. Eg. Mario Kart 8 = £49.99, Super Mario Kart = £5.99 so the price for Mario kart 8 would be £44. Something to research if you are getting the digital version.
