For me it is the best first-person shooter (despite RPG proportion they are the one for me) this generation.
If one follows the story only in passing and does not worry about the basic idea, which is behind the city of Rapture, this still captivates from the very first second.
On the disc, all DLC's and the games are themselves are up to date, so you really need to download anything.
Who has little memory, should bear in mind that almost 22GB are claimed (for all data). This is also on the packaging, perhaps even someone here once upload an image.
In addition is really all uncut, there are virtually no differences from the PEGI version!
For 20 an absolute must-buy
Addendum: From Speicherbug I can not tell, because it did not occur to me. Possession however, the USK version
