I never played New Vegas. I stopped at Fallout 3 and was going to wait until all the DLC came out for NV, but… then Deus Ex 3 came out…
I remember the DLC for Fallout 3. Putting it all together it was about the length of a second game. So if you like open-world games, yeah it’s probably worth fifteen human dollars at least.
On the other hoof, what would you do with those ten dollars if you didn’t get all the DLC?
