If you never had a Wii, don't forget to look into that console's fantastic line-up, too. The Wii has my two favourite 3D platformers of all time and my favourite Action-Adventure of all time: Super Mario Galaxy, Super Mario Galaxy 2, Zelda: Skyward Sword. Get them! Also on Wii U, you should not miss Super Mario 3D World and Pikmin 3, but there are also a whole lot of other fantastic games on both, Wii and Wii U for you to enjoy. If you don't plan on buying digital, 8GB is just fine, but the NSMBU+NSLU bundle has a 32GB and those games are incredible, too. If you buy a 32 GB, you also get a sensor bar with it, which you need for Wii games (provided you want to play them on the tv), you then just need a Wii-Remote Plus and a Nunchuk to be able to play most Wii games, while also being prepared for multiplayer on Wii U.
