Which DLC should I buy?

well, I have considered:

The Knothole island for fable II

Fallout 3 the pitt

The sky is falling, mass effect

Lost and damned gtaIV

Recommend any other, do not recommend versus mode (RE5) nor map packs.

Thanks

Lost and the Damned. It has the most content and will last you longer then any of the others. I also enjoyed the new missions and story arc.

If you like bikes and GTA, then Lost and Damned.

gears of war 2....2 new maps

I'm guessing you've played and enjoyed all four games so...

I've played all the games and have the DLC you mentioned - they're all great additions to the games. Lost and Damned is the biggest bang for your buck though. It's got tons and tons of content.

If you are looking for the most bang for your buck Lost and Damned is your best choice. The Pitt for Fallout was fun but it isn't worth the 800 Micro. points
