This game is on sale. I've never played one of those before.

Arguably so. It's got 60fps and the most up to date graphics but has the least amount of songs and most of the game is locked behind grinding and rng, unlike the other entries. In terms of difficulty it's behind Future Tone and edit mode in F/F2nd.
I'd say try the demo of it along with Future Tone Prelude and see which one you like more. The Future Tone bundle is on sale too I think.

Maybe, not really? It's got a silly story mode in it for some reason. I'd prefer just to play freely and unlock shit by playing like all the games before it but at least you unlock the hard difficulties right away after finishing the story, I guess it balances out

future tone is what you want.
