OK, I'm going to to make this quick: Fallout 3 rocks. Unlike many other RPG's, everything you do has a realistic consequence. If you kill someone, they stay dead, you get unique dialouge options, and an entire settlement may change. You are free to play the game however you want, either being the paragon of goodness or a Complete Monster
(I usually play as something in between, but I'm almost always on the good end of the karma scale). This is Fallout 3's greatest strength, but another thing I like is that many of the quests are morally neutral, and nearly every character in the game can give you one. I have mixed feelings on Fallout 3's combat system though. It tries to combine FPS and turn based combat, and does it really well, but there is one problem: Turn based combat is not
exciting. It sometimes kills the tension in otherwise awesome battle scenes. The over reliance on the V.A.T.S system and the fact that most guns can't hit anything beyond 15 feet also greatly limits the skill you can actually use in combat. Regardless, Fallout 3 is an incredibly immersive, varied, and overall awesome experience. It really sucks you in, and I highly recommend it. 9/10.
