For me, it was sitting with the wider family last night, with the current Mrs T, my two daughters, and playing Mario chase from 7 - 9:30 last night.
The reason why its a special moment, is the last time we did this, it was Mario Kart 64 many moons ago and both my girls were still at home and going to school. My eldest Daughter has now left home into her own house, and the other has just turned 21. Its been a very long time since we played a game together and more importantly, had a fantastic time. Worth every penny I paid for the Wii U for that night last night
