Risk was just between my brother any myself, so it was always a bit of a stalemate till one of the dices goes on a rampage and destroys all the opponent's troops :)

Risk is also good for Geography as it helps to visualise the continents on a flat map. I do miss playing Risk now we are talking about it. 

Nintendo switch is also great, just make sure to get those more family oriented games like Mario Cart/ Mario Party/ Switch Sports whereby a group of people can play together.
