Personally i was dissapointed with dead money.. I mean, fantastic story line, and being assoiciated with the brotherhood makes that even sweeter. But imo i much prefer add ons that simply add to the already incredible map that fallout has. The whole atmosphere of the sierra madre is great, but personally i think it would have been better to have a town/village/hideout/bunker etc in which there IS a small community of friendly people.. I dunno i think it just adds a bit of freedom to me.
Not to mention the fact that you can never go back once you leave, that basically puts all the pressure on you to make your £8 worth it before you leave. I hope Honest Hearts is a bit more like point lookout or the pitt.. but this time, don't make it so you have to go over a boat or something and leave followers and your favourite weapons etc waving you off from the docks.. eh Bethesda?
