Development has started on Music Maven 4. More details will be announced as they are made available.

Music Maven 3 saw the addition of much more content and depth to the simulation engine. It was a major step forward in the game, including the following improvements over Music Maven 2:

 - Completely customizable band lineups
 - Each song could appear on a single AND an album
 - Allowed setting of track order for each recording
 - Maven Mall: Could purchase items for individual musicians such as instruments
 - More content such as additional venues, studios, and cities
 - Interactive map to locate venues by continent
 - More immersive musician tracking with Musician photos and bios
 - Added genre-level awards (added after initial lauch)
 - Added festivals (added after initial launch)

Due to the unexpected success of Music Maven 1, it quickly became apparent that the game would need to be upgraded to support the growing user community. As such, Music Maven 2 was a complete port/rewrite of Music Maven 1 from ASP/MS-Access to PHP/MySQL format.

It was during Music Maven 2 that the game's popularity really exploded. As of June, 2003, there were approximately 2000 active bands in the game.

 
 

Music Maven Online 1 originally started merely as a detour while development was continuing on the more in-depth desktop version of the game. In fact, here's a posting back on 2/25/2002 first announcing the game: "Lately I've been working on an online version of Music Maven. The online version of Music Maven is a scaled-down version. Since it doesn't have as many features as the desktop version, development is much easier. I wanted to do this online thing so I can at least get something playable out for people to play with. I'm hoping that feedback on the online game will help with the development of the desktop version."

The game was written in ASP against an MS Access database, which soon created performance problems. But during this period, the player-based was still under 100.
