I want to buy us a Switch as a family Christmas present but am pretty clueless about gaming systems so could do with some pointers about things to buy/avoid. We have a very old Wii and the kids love Mario Cart, Wii Sports, and Wii Fit so will want to replicate those types of games, us maybe some others, they also like Minecraft and Sims on the PC. Any other games to look out for? Any must-have or must-avoid accessories? Anything I should know about how it all works?
