I think of Spiral Knights as the Zelda MMO. The gameplay takes me back to Nintendo and Super Nintendo days. The setting is obviously rather different.
What if you took Zelda in a different direction and decided that chopping down tall grasses in search of rupees was the heart of the game? I give you: Bush Whacker 2. Zelda, minus the monsters and game elements, plus the standard social media energy mechanic and cash shop. I do not have endgame experience, but I think I just summarized the whole thing. (It also has a quick-whack button, in case you find tedium tedious.)
It is strangely hypnotic. I have yet to research what happened to Bushwhacker 1.
