That only mentions the Final Fantasy series. Almost zero rpgs outside of FF use an ATB variant. I'm talking about outside of FF. DQIII and FFIII were precursors to FFV, but the way FFV did its ability system has been copied over and over, across srpgs, to FF sequels, to games without the FF title in their name. Specifically, it is a heavy influence on FF Tactics' job system, which has been copied a million times.
FFV clearly has inspired a lot of games, whether it's Blue Dragon, FFT, or Disgaea, you can see FFV's influence far and wide.
Other FF games mechanics, outside of maybe X's monster order feature, aren't a genre mainstay like FFV's job system was.
