i mean its kinda the smart thing to do. wii u sold very poorly so not many people got to experience its library. so makes sense for them to re-release the best games of the platform onto the switch. but yeah part of the reason i skip out on many switch titles is because i have already played them on the wii u. even when the wii u ports has meaningful additional content, like with mario 3d world, its hard for me to drop another $60 on it.
