So I've got the GOTY edition of Fallout 3 and have finished all side quests from the MAIN game (940GS, only have kill 300 people and Take it Back achievements to go) Can i still play after the last main story mission? Should I complete Operation: Anchorage and The Pitt first, finish Take it Back then continue playing via Broken Steel? How should I go about being able to play everything as well as getting all the achievements. Thanks.
