When I reviewed the the Wii U last year I gave it an 8/10. If I were reviewing it today, having used the Xbox One and PS4,I am not sure I would give it the same score, but that doesn't mean it's a bad console.
As ever, Nintendo has always had its own way of doing things, and that is no different from the Wii U, making it the console that offers something a little different than what the mainstream guys from Sony and Microsoft give...so I would say it pretty good, go for it..
Ohhh, goodness, before I forget, there is one limitation. The battery life on the Wii U GamePad is close to awful, with around three to four hours from a charge in our experience.But the the two answers to this are to keep it plugged in to its charger, or play in bursts and remember to recharge between sessions.
