i think i own more physical wii u games than switch :p i bought it late in the gen though when switch had just released and everything was (relatively) cheap
i got bayo and bayo 2, xeno x, 3d world, botw, smash (my friends dig it, bought the switch version for the same reason), smb u, mk8, dkc tropical freeze, zombi u, ww hd. it's a good console to have around, being able to hack it easily means you'll always have a console able to play gc and wii and have access to all the virtual console titles even if nintendo shut down access from their digital storefront. wii u rules.
