Prometheus and Aliens: Colonial Marines game

Hi there, forgive me if this has already been mentioned but i couldnt see it anywhere. Reading an interview with the producer of the Aliens: Colonial Marines video game Brian Burleson on the newspaper Metro's website (sorry I don't know how to paste the link?) i found this quote interesting 'When we first spoke to Ridley we got some info on how things worked, but for the most part during the filming of Prometheus we were in the dark as well. It wasn't until the very end that we got to see more. And thank god it was all consistent with what we had in the game,' he added. I was under the impression that Prometheus was only going to be set in the same universe as Alien and would brush aside the events from Aliens, Alien3 and Resurection such as the Queen etc as they were nothing to do with Ridley. However as this video game is set directly after the events of Aliens it suggests that for continuity issues the events in Aliens are also consistant with what happens in Prometheus?
