Consider it a third. Also, do your research in WiiU as much as Wii. Despite poor marketing, they are considered different consoles in the gaming community for good reasons in their own right. That said, my poor understanding is WiiU is more portable and the "missing link" between the Wii and the Switch. I'm more a proponent of the Wii alone so you have more time with your child when away from home rather than having them sucked into the digital world when you have intent to connect with them. That way, when its at home, it stays home. Speaking from experience of the child in their own digital reality during family events... Sometimes used as a coping mechanism now. Anywho, While they are young, they may enjoy WiiFit, too. Nothing beats playing catch with Dad, though.
