So if this add's nothing to the base game...whats the point? really all the dlc is...is a quest mod, so for us on the pc who can't get it, we really are not missing much cause there are lots of great mods for free, if it does come to pc I'm fairly certain I won't pay $10 for a quest.
Well, if you're on the PC, mods will undoubtedly come out that use DM resources. I mean, that was the only reason to buy Zeta after all.
Anyway, from what I'm hearing, DM seems more like it's a different and self-contained experience to NV vanilla. It certainly sounds interesting, and it adds some neat guns and armor and stuff.
In fact, if you're on the PC, there are already several mods that add more combat to the game, so a DLC "dungeons and raiders/muties/enclave" mod isn't as necessary for us as it would be for, say, the 360ers or PS3 guys.
