You may build any theme, type and genre of game you want. This game may contain one level or multiple levels, as long as on the whole it fulfills the requirements of one subject from the teaching list.  If you'd like to submit a different middle school teaching subject, you may apply here.
 
You may build a game entirely from scratch, or you use an engine that has already been built. We believe your chances of building a successful game will improve dramatically with the help of pre-built technology—however the more structure you begin with, the less opportunity you have to uniquely incorporate your teaching subject. Please consult the list of development tools to see what's acceptable. If you would like to use something that is not on our list and have a strong argument for why, hit the message boards with your recommendation.

You may build your game on any platform (e.g. PC or Mac) and with the intention of the game being played on any platform or console. For example, if complex graphics are not a team strength, you may consider building a game that is meant for a portable console such as the Nintendo Gameboy.  If you are building for a PC, you must build your game for Windows 2000 or a subsequent operating system.  If you are building with a console in mind, it must be a console that is currently available on store shelves.
 
All concepts, design, art and sound must be original.  Your game should be built with an eye toward generally acceptable aesthetic and sound qualities.  In other words, no "choppy play" or "poppy sound."
 
The Hidden Agenda team reserves the right to build your game for a platform other than the one for which you designed your game.  We also reserve the right to, or not to distribute and/or sell your game through whatever distribution channel or method we see fit.
