disc version or alternative means

There is a physical version of this game that has all the content on disc. No need for a subscription or additional purchases.

is there a alternative??

if you have hshop/3hs [which i think is only on 3ds] you can get dlc for free

yargh matey (catching my drift?)

You can download the dlc from wii u downloader without any problems.

nuspli should have all the DLC for it.
