HLD - it's a great entry point for new players or for those who are not familiar with the system
CoTG - first part of the draconis strain saga; Also good starting point for new/returning/old players that want to jump in A-RPG
DoW - second part of the draconis strain saga; Can be a very long - mini campaign cinematic, it's good for the Game Mother to read the cinematic more then 3 times IMO
CMOM - Colonial Marines campaign; Can be played alone or as continuation from DoW
HoD (Heart of Darkness) - third and final part of the draconis strain saga (can't wait to pre-order it!
)
