My usual Good vs. Bad review (MAY CONTAIN SPOILERS! You have been warned)
The Good:
~ The games story is a simple, yet amazing one that has many different paths you can choose, all of which change the outlook of the game.
~Good? Neutral? or Evil? Choose by your actions, and see how people react to you as you even simply just walk by them, you can even hear most of the actions you have done from quests on the radio.
~The apocalyptic environment is amazingly designed and planned well, making the game a beautiful, yet at the same time weird and disturbing.
~While on the subject of visuals, i'd also like to point out that the sound design is also very well-done.
~The time of play for the main storyline alone is 14 hours (at least that's how long it took me my first time), 60 hours if you are willing to do all the other quests, and about 100+ if your trying to get all the achievements. This game will last you a long time, trust me.
~The enemies in this game are all fun to kill and each have their own combat style.
~There is a wide selection of weapons and armors, as well as ones that are hidden AND ones you even must make yourself, don't worry, the weapons you make really aren't all that difficult to make at all.
~There are over 100 different locations to visit within the post-apocalyptic Washington D.C.
The Bad:
~The radio stations can get rather annoying after awhile for the fact that its the same 5 or so songs and the radio-stations host repeating themselves over and over....
~Once you beat the main story in the game, or even enter the last room at the end, you can NOT do other quests or travel, your kinda forced to start over...
That's about it, overall I recommend this game, even if you have never played an RPG before... However, if you really haven't then you should rent first... If you have played an RPG before and know how games like this work i recommend just buying it, with over 150 hours of play and a rumored expansion, this is a game that will keep you occupied for quite some time!.
