I wasn't meaning to, or attempting to compare it to Borderlands or Fallout. My main gripe with it are the missions. they are extremely simple and OK, granted, some do stand out, i.e dead city, but most of them are pretty weak on content. Like spending a few minutes travelling to an area for a quest item only to find that it's either deviod of life or there are a few bandits that can be dispatched within seconds.
There's all this fantastic detailed world, which begs to be explored, but there's rarely anything to find, bar bandits in their buggies trying to shoot you to pieces.
It's definitely not a bad game, far from it. I just think that with all the development time they could have made it more robust. But then, maybe I am being too hard on it. This is all of course my opinion, I respect that other peole are enjoying it.
