Why do you play FFR (the game)?

[qqwref]

I think everyone here knows that FFR isn't exactly the most fully-featured rhythm game around. All the charts are 4-key; there are no holds, mines, xmods, or marvelous judgments; the game isn't as flashy or customizable as some others; some songs are entirely blue arrows; and so on. Stepmania's been around for years, and is objectively a far better game.

And yet, despite what some might perceive as drawbacks, we still play and enjoy the game itself. What are your personal reasons for this? Is it the high scoring system and the competitive shaving of goods, or the nostalgic and set-in-stone gameplay, or the accessibility and simplicity? Or something else entirely? Don't think about the community, since you can be part of it without actually playing the game - just think about why the game itself keeps you playing after so long.

So, let's discuss. I think the community's answer to this could influence the future direction of the site.
