I'd say so, but if you're not sure you can get a Wii Mini and some of it's best games for less money, and all of the Wii games will run on the Wii U if you decide you like Nintendo games.
Thank you for response, @grahamf. I think I can say i like Nintendo games but i haven't ever played this titles for WiiU and I just want to know if they're as wonderful as they look on YouTube. WiiU in my country is quite expensive.
So are games. I want to be sure if it's not waste of money. What do you think?
