MirthKit

MirthKit is the downloadable arcade where the people who make your games are just like you. There arent any big companies, and many of the games made on MirthKit are created by a single creative person. Many games on MirthKit are free and many are for sale. Regardless of whether the game is commercial or not, its yours, so you have full access to its inner-workings, at least if you are interested in that sort of thing. Since everyone has access to all parts of a game, an important part of MirthKit is adding on to existing games. So, if you enjoy a particular game, investigate what else is available for it, or even plan your own expansion for it.

Requirements:

Windows XP/Vista
