6. Once, Twice, Three Times An Achiever - Fallout 3
Not only is one playthrough not good enough for this game, twice isn't either. In order to effectively acquire the ranking achievements in Fallout 3, the game must be played three times. In each playthrough, the player must decide to be good, bad or neutral. While this may be one of the more enjoyable achievements on this list, it is easier said than done. With each play on each different moral ground the game changes pretty drastically. From the way you are greeted in the Wasteland to the missions that unlock, each experience is unique. The suite given to you in Tenpenny Tower is much more lavish than the dump in Megaton, so choose wisely. Sidekicks such as Dogmeat and Charon will work with you or against you based on past conversations, missions and ultimately, karma. One of the nicer, more subtle features in Fallout 3 is your presence on Galaxy News Radio and how you are perceived by local celebrity, Three Dog. He will either sing your praises or call you out for your wrongdoings and it's always fun to get a shoutout, no matter how bad it hurts.
