If you want to create an ASP game you should check out Project Rockstar. The game gives you the opportunity to be a band Manager with up to 10 bands and the chance to create your own Record Label. You can hire/fire musicians, instruct them to write songs, gig, practice and promote in your quest to make as much money as possible.
Created by kerb and coded by two guys (Chris and Robsa), the game has evolved since it was first released by Vizzavi (who later went bust) in 2002. Relaunched by kerb, the game has thousands of active managers, extensive forums and an in-game email system. The game was Reset at the beginning of August so that everyone starts from scratch, allowing new players the chance to do as well as more experienced player. There are some very neat touches including hidden forums that require you to purchase a licence from the trading area in order to participate - and it's all ASP.
