Dealspwn: This upcoming version of Destiny is packed with value as it includes the original Season Pass expansion content (House of Wolves and The Dark Below) as well as the upcoming expansion The Taken King. This is much cheaper than buying the content separately.
There are some radical changes to the way the XP system works in Destiny too when The Taken King arrives. Essentially, the annoying Light system that forced you to equip certain items if you wanted the level boost is being replaced with something similar to the way you levelled up on the way to Lv.20. These are exciting times and it looks like Bungie are making a solid effort at bringing lapsed players back and giving them all the content in this edition seems like a smart move as it's only about £10-£15 more than the base game now.
