No, because CONELRAD/ any radio mod really is free.
I won't pay more money for something that should have been more extensive in the first place; if you can't afford to pay the VA more, get a less-known VA who'll work for less and record more lines.
As gamers, we really don't need to encourage companies releasing like one new item and calling it "DLC" like Bioware seems to be fond of doing. Stuff like that should be free in patches; DLCs should be like The Pitt or Point Lookout, proper addons, not tiny bundles of content that should be free in the first place.
Hell, I'm inclined to think that all DLC should be done Valve-style, but they're a rare breed.
I agree with you 100%. Radio New Vegas should have been more extensive in the first place to begin with so no sense in paying more for something like that which could have been a much better addition to the game environment. I would not pay one red cent for more content on RNV. I actually have a long list of similar complaints about other aspects of the game. I think overall, this one fell short in comparison to previous FO versions that have come out.
