Fallout 3 is an amazing game. It even has a non-linear storyline. For all you people that don't know what that means, it means you can do practically anything! As soon as you leave the beginning stage of the game, you don't have to do the storyline, you can just do side-quests! Ah, hell, who am I kidding? You don't have to do anything! You can just go kill radioactive monsters and savage raiders! You can do ANYTHING!
You probably should do other stuff, because the main storyline only lasts a small amount of time. However, with the edition of the expansion Broken Steel, the storyline gets considerably larger. Luckily for you, Broken Steel (plus Operation: Anchorage, The Pitt, Point Lookout, and Mothership Zeta) is included within the Game of the Year Edition. Yup, every DLC (Downloadable Content) is included in the GotYE!
The 28 quests in the game itself should keep you busy for a long time! Imagine how long you'll get to play the game with 5 Expansions! Countless Quests and thousands of armor/weapon choices, you could play this game for years (or until New Vegas comes out)! I've gotten a chance to play all these, and I had a lot of fun!
Operation: Anchorage was extremely fun, adding 4+ Hours of gameplay, it's amazing. The only problem is, it's rather linear, and the ammo/health dispensers make the DLC easy, even on Very Hard mode. I don't want to give away to much, so I'll stop here.
DRAFT: WILL FINISH LATER
