This is well worth the buy, not only do you get the game which takes about 30+ hours to clock but you also get every single DLC, yes EVERY ONE which will take you fair bit of time to do for just 20 pound.
All the DLC is great, you will save yourself alot of money buying this than buying all the DLC from the XBL market place. I have had this for a month now and still have not done all of the DLC 20 pound for a months worth game is just too good to miss.
I will now talk about the game pros... The pro's of this game is the amazing dialog, never have i felt so involed and attached to charcter's in a game, the voice acting is just amazing, the combat system is great too, many side missions to keep you entertained including compainion missions which i really liked because i would find out more of their life stories.
Only con i can think of is that the main charcter does not talk but keep in mind this is not a major con at all, just hoped the main charcter would talk. This game is deffo worth the buy there is a reason why it was game of the year 2009.
