Quoted from Jgel:
Is it worth it is you plan to never build a level? Are there a bunch of levels that you can just play offline?
There are 100 levels (maybe more) in the "Story mode", and even if you don't build any - if you are online, there will just be unlimited levels to play that other people are making.
Also, I forget if this was mentioned in this thread. But if you have Twitch Prime (free with Amazon Prime), you can get a FREE year of Nintendo Online...it works even if you're paying for it already, it just stacks onto your subscription.
Even if you don't have any online games, it allows you to download & play the NES games and Tetris 99 for free.
