Cannot compare to Fallout 1 and 2 in any way, but a great game.
All the DLC is great content.
It can get a bit boring after some time, and at nighttime it gets a bit too gray. But Bethesda did a pretty decent job. If you like shooters and rpgs, you really should go for it. But specially, if you like post-apocalyptic themes AND 50's music! The wasteland radio is awesome.
