8: Armed Assault: ArmA
In the mid 2000s, Bohemia Interactive, creators of Operation Flashpoint, parted ways in anger with publisher Codemasters. This left the OFP license with the publisher and the developer with a half finished successor to their 2001 surprise hit. So eventually BI found a new publisher, and rebranded the game, which resulted in the birth of the ArmA franchise. Armed Assault follows the same pattern established by OFP. An enormously huge island level, a fictional, contemporary conflict, relatively open ended mission structures.
