Design a game that enables and encourages players to make and share some kind of art: story, poetry, music, drawings, etc, etc.
Hmm.. my game ideas i think would be about a music game. As I use to play around with garage to make effect of my instrument, which is fun to choose the effects for my guitar, I want some kind of instrument effects chooser on my game.
So I want a computer game, which could be a multiplayer or single player. It is started that you have a band with your friend that had just formed in your garage. and you can choose what kind of instrument that you want. And not long after some one got ideas of a song to compose. So your task is to help your band member to compose a song by simply clicking the style that you want to play for your instrument, the effects and so on.
You could compose the song base from the scratch (maybe hard for those who know nothing about instrument), but you can let other player that have know how to do it then you help, or let computer to start the ideas of what song to compose.
Also, It would also give you budget of buying your effects, customize your instrument, also you can share the song that you compose and so on… So the band would start the carrier from garage and if the songs become popular, it would become one of the big artist later on..
