Future TomTom is the best fucking Bemani game ever. It doesn't seem to have a very high difficulty ceiling (as in, i was AA'ing 9's on my second credit, and the game only goes up to 10), but I don't give a shit. It's easily one of the most fun rhythm games I've ever played.
So, two accomplishments, I guess: 1) playing it in the first place, and 2) getting a AAA* on a 7 out of nowhere.
I might have to try to get a video of me playing it next time I'm down there. There don't seem to be many gameplay videos on YouTube, especially for higher level stuff (though admittedly I didn't look too hard).
