I just saw it in the store

It is said to be an uncensored version but what else is in there.

how do i know if i played the censored version or the uncensored version?

My game was EUROPE one

Contains all the DLC and the full game 

instead of just the game or just the DLC 

I saw this in Gamestop a few days ago.  How does that work for the 360 version?  Two discs?  I know the DVD was full for the original version of the game.  Either way, I already own both the game and the Episodes discs.  Just wondering.

that would be 2 discs

GTA 4 was 6-7gbs,don't know about the episodes but they should take around 4gbs so 1 dvd 9 and 1 dvd-5 is needed

i too have the original game and episodes but read on some forums that this is the uncensored version but i don't know if mine of censored or not

Me neither.  I never finished GTA4 (I finished the funeral gunfight and never played it again).  Then I bought Episodes and played about an hour of Lost and Damned and about ten minutes of Gay Tony and never touched it again, either.  I heard there was full frontal nudity in Lost and Damned but I never got that far.

I guess two discs;..And probably has to install the second disc (with the DLC) to play it.

I doubt it. Probably stand alone playable just like Episodes From Liberty City.
