Fallout 3 is a good game,
but just not what I see as prequel to the two original titels.
The athmosphere is somehow similar but not really the same.

Things like: "you are not allowed to sleep in this bed, it belongs to someone else" (as if the Playercharacter would give a shit in the original Fallout),
or invicible children, or loosing Karma already by stealing a spoon, or having already a fat gun quite quick.
are just some examples of it.

Also everyone knows that you are a vault dweller, and how it is
to be in a vault. Making this vault thing not mysterious.

This is ok in a new game, but it really bugs me
when looking at the former freedom of the fallout world.
