To play Physically, you need a digital membership subscription. Non-Physical* play does not require a membership subscription. Go to the FAQ named "How much does the game cost and how do I get it?" for more information on how to purchase a membership or bundled package.
Try any plan risk-free, and get a full refund on a purchased membership subscription if canceled within 7 days. Smashometer Bundles provide a 30-day money guarantee.
No live support is available for the free (for now) non-physical version of the game.
