What you just said is true for
www.thecoli.com/arcadium and other forums
In the real world, Nintendo is the only company consistently delivering games that appeals to kids and even adults
You just gotta actually play them instead of going online and asking a bunch of 20yr old white kids who jerkoff to porn sites multiple times a day
Not only will your child love the OG wii let alone a Wii-U. You probably don't know much about soft-mod
Let me indoctrinate you bruh bruh

All you need is a regular SD card. You insert it into your wii, follow the instructions.
Then you can play any Wii, Wii-ware, Gamecube game for free. You can use an external HDD or even an SD card (or a flash drive, whatever) to store the games.
You can have all this for under $100 easily. My OG wii died, I copped one for $40 off craigslist 2yrs ago. It still works. If you need any help in the softmod process, myself or plenty of others will help you out
