Is the third entry in the series of RPG Maker programs by ASCII. It is a video game creation program like other games in the series. Based on RPG Maker 2000, it builds upon the old RPG Maker 2000 features and includes new features such as an improved default tileset with more detailed graphics, a new third person side-view active battle system, and additional database options. Most of the features present in RPG Maker 2000 are in RPG Maker 2003. It is also able to convert RPG Maker 2000 games into RPG Maker 2003 games after the database is accessed. This makes the game have features that RPG Maker 2003 has, such as the side view battle system, however, this makes it impossible to open it in RPG Maker 2000 again as it cannot convert RPG Maker 2003 games back into RPG Maker 2000 games. The database now includes customization options for customizing the side view battler's animations.
