For those who don't know stepmania is rhthym game that is an exact replication of DDR. The game allows keyboard and pad use and for the android we'd probably use touch and keyboard (for devices that have one). There are few rhythm games on the android market and this would make a great addition. Stepmania is fully customizable and people can add their own announcers, themes and best of all any song of their liking. I think it would be appropriate if all this was loaded from an SD card. Here is the link to the website StepMania: Free dance game and songs - play with dance pads - play DWI and SM songs - not affiliated with Dance Dance Revolution Here is the link to info for developers Developers yeah so i think thats it...... Also if you don't want to port something so big (if thats big) You can also try FFR (Flashflashrevolution) FlashFlashrevolution.com (written in flash) Basically the same thing but for browsers and is exclusively for the keyboard.
