Overall, what makes Fallout 3 such a phenomenal experience is the cohesiveness of the whole game. From humorous and interesting NPC's who you legitimately want to know, to engrossing sounds and sights, there is very little not to love. The game's total length is fully up to the player; you can literally spend hours on side quests and avoid others entirely. Games Abyss is told a full play through (if such a thing is possible in a game this dense) can take upwards of 100 hours. The amazing thing is every single play through will be different. This is definitely a must-play for any gamer (if you can consider yourself such without having played Fallout 3).
