Pirates CSG Online was a downloadable, internet-based adaptation of the tabletop strategy game Pirates of the Spanish Main.
Although most of the core rules functioned exactly the same in both versions, there were several minor differences in the online game (generally due to limitations of the format) that had a considerable effect on gameplay.
The online game included the following sets from the tabletop game:
- Spanish Main
- Crimson Coast
- South China Seas
- Davy Jones' Curse
- Mysterious Islands
- Ocean's Edge
SOE ceased support of the game on January 31, 2011 and it is no longer available.
