Long story short, THQ have basically announced that Dark Millennium is not going to be an MMO anymore but will be shifting to a something more akin to Space Marine broadly content wise, a singleplayer campaign experience with "traditional" multiplayer (for lack of a better description). Now you may remember how in the past THQ, or Danny Bilson to be specific, said that there was some overlap between Dark Millennium and Space Marine and that a Space Marine sequel was possibly unlikely even in spite of good sales figures due to said overlap. So with this recent news, something which we would assume THQ had on the backburner just in case they couldn't get the funding to bring Dark Millenium to market as an MMO unless it was a snap decision, it seems that the future of Space Marine as a franchise is now further up in the air due to how similar the two games rumouredly are, like the combat mechanics being quite similar to each other.
With this shift in emphasis from a MMO to something more akin to a "traditional" Action release both the development teams at Relic Entertainment and Vigil has been slashed in size, which should also theoretically save THQ some money on development of Dark Millennium. So basically, does this shift of focus and resources by THQ in regards to Dark Millennium basically put a nail in the coffin of Space Marine as a possible future long running successful franchise developed by Relic if the two games are as similar as rumoured?
