What we need is a good idea of dance game (but everything was already exploited), or team up with Konami to create a Dancing WipEout AC. But it will be all original new songs, with double this time.
Like you said, with my stepping skills, and community skills, we can create the successor of ITG, but more DDR accurate ? Some mash-up with DDR like ITG/PIU PRO.
An idea ...
