Playstation 3 gamers will be able to get their hands on the first Mass Effect game when it's released as part of the Mass Effect Trilogy on December 7 (it'll also be available to download separately on the Playstation Store).
Xbox 360 and PC owners will be able to pick up their versions of the collections a month earlier, with a launch date of November 9 planned. Interestingly, each of the different versions of the game comes complete with different DLC (details of which can be found here).
