I don't know why, but Fallout 3 just didn't stick to me. Tried playing it, but the gun combat seemed stiff to me.
I guess it isn't for everyone. But, the combat and the game in general was very buggy and unreliable. Some people argue the story wasn't original enough and too predicable. But, I really enjoyed every aspect about the game. I did predict what was going to happen very early on but I didn't think about it too much and carried on. The multiple choice factor really made it a little bit better because you could replay it and have a different outcome. The combat wasn't very realistic and was very easy to manipulate. But, I still enjoyed it.
