Publishing Philosophy

Unlike commercial publishers, AGD Interactive operates as a non-profit organization, releasing all of their remakes for free.⁷⁸⁹ This approach allows them to maintain creative independence while avoiding licensing complexities that would arise with commercial development.¹⁰¹¹¹² Their games are distributed directly through their website and various abandonware/freeware archives.¹³¹⁴¹⁵
