In recent news Fallout 4 has been confirmed by Pete Hines to not have any timed exclusive DLC content. A warm sight to all of the timed and exclusive DLC deals going on with Call of Duty and Destiny. Today I am going to remind you of the "deals" and pre-order content of the previous Fallout games.
Fallout 3 is an insanely fun game; but that doesn't stop it from being guilty of 'timed exclusive DLC.' The Xbox 360 and PC received all of the Fallout 3 DLC in between January and August of 2009, while PlayStation got it all in September and October 2009, as sourced here. One thing I find interesting in this, is that it happened so long ago when you would've thought this stuff wouldn't of existed.
Fallout New Vegas (made by another developer) had nasty pre-order bonuses. As quoted from the Fallout Wikia "Players pre-ordering Fallout: New Vegas from selected retailers were granted access to special pre-order bonus packs, containing exclusive equipment to make the earlier stages of the game easier." There was four of these packs in which you could only get at different retailers.
It's a nice thought they changed this with Fallout 4, especially in this time of insane pre-order bonuses.
Fallout 4 is releasing on November 10 for current gen consoles (besides Wii U) and PC.
