As you can see, the main TTB franchise can be divided into various subseries. And that's not even counting some of the spinoffs.

This goes the same for ACS' other rhythm games as well. rhythmic_touch averts this by staying number well into its 25th installment (besides console ports, which are counted through letters instead)

Hell, Karaoke Superstar(s) is actually the name of TWO concurrent series by ACS.
