Celebrate National Siblings Day on April 10th with Nintendo

For those of us who didn't already have the day marked on the calendar, this coming Friday (April 10th) is none other than National Siblings Day. Given that Nintendo are the custodians of the most famous brothers in gaming, namely Mario and Luigi, it would be odd if they didn't get involved with the festivities in some way or other. It all sounds like a good excuse to run a competition celebrating the day with the grand prize of a brand new Nintendo 3DS XL system and Nintendo eShop gift card up for grabs.

Here's the full lowdown from Nintendo themselves:
