MK8-WiiU is alive or completely dead?

I only have money to play on my Wii U and the servers are functional. I don't know if there's still people playing it competitively.

Hello! Yeah, Wii U scene's quieter but still got some die-hards. Check out Discord or forums for groups. Might find folks up for a match!

Unfortunately, the online services for both the Wii U and 3DS are ending this April, so you should play it while you're still able to.
