Mass Effect 3 has a lot of DLC already on the agenda but let's say you want all of it.
It will only cost you, well, $870. Well not exactly, the guy didn't take into account that the DLC that comes with the merchandise is one and the same so really it's closer to $240. Heh,
only $240!!
A lot of it is inconsequential stuff like weapons for multiplayer. That mode sounds neat, would like to try it, but after playing the demo, I can say I will never ever go to such depths as to buy content for it. All this multiplayer DLC is guff considering it's not what fans are coming to ME3 for in the first place. No, perhaps the biggest offender is the 'From Dust' Day One DLC. Not only is it the most expensive DLC at $10, but it also has a party member that's hidden away in the main game. Not much different to what happened with ME2, I hear you say. Except this time, this particular character is fairly integral to the overall story. More than that, the DLC apparently ties up loose ends not covered in the actual game. So in essence, there is an ending to ME3, but it's not the 'real' ending, that you have to pay additional money for. Bullshit.

Really though, imagine it like, 'Want to see the final 30 mins of The Godfather? You need to buy the Epilogue pack on the Marketplace!'
