According to some on Vgchartz, one-three games is enough reason to buy a new system, so why is the Wii U "not worth it" to some?

Maybe because Xbox One and PS4 actually have 3rd parties backing up the exclusives? Hence not having to wait on 1 new game every 3-6 months

This.

And almost all WiiU exclusives cater to a same or similar audience, while X1 and PS4 spread their wealth across many genres and target more audiences.
