Nighsoft is a company that clones and modifies classic games. It's intention is to provide the means for classic and abandoned games to continue living on forever as open source. Even though the games Nighsoft produces are open source and free the public servers Nighsoft runs for these games are not. If you like any of the games that Nighsoft reproduces and advances then please support their efforts by playing them.
Nighsoft is currently dormant.
