What's the most disappointing game system you've ever owned?

[Loneken]

WIIU.
I have NSMBU, Bayonetta2, Yoshi,Mario 3d World,Xenoblade and the 3 Zelda games. Great games but the console has nothing more.
Even in my Xbox One i have more that 50 good games (Without counting BC titles) i really regret buying the WIIU

Sorry for my bad english.
