- Do not screw up the controller
- Do not screw up the songs
- Do not screw up the graphics
Just remember: anyone will step around on a dance pad and have fun. The Beatmania audience will be mostly gamers (and hardcore ones at that), so make the game to reflect that. Don't strip out hard songs. Don't add in US covers that would be boring in Beatmania. Don't make US mixes with half as many songs as the Japan mixes and charge the same amount of money. Don't say "I don't think most Americans will like Memories so we'll just remove it last minute, even though it's free for us to use, but we'll keep the song embedded in the game, tricking the game into thinking that Memories is playable, even though it isn't, making it impossible to master the game".
