Interstate '76: 2 Open Source Clones Compared
Interstate Outlaws is an original vehicular-deathmatch game built on the Crystal Space engine, inspired by Interstate '76 rather than reproducing its actual content — it ships its own vehicles, maps and weapons rather than assets tied to the original game. Open76 instead is an engine reimplementation on Unity that parses and renders actual Interstate '76 level and vehicle data, requiring an owned copy of the game's install directory; its car simulation (engine, gearbox) is still unfinished, though driving and camera modes already work.
