D2 problem was that it wasn't bigger nor better than D1... the money items were not the deal breaker ( that's been way overplayed )
It was simply not enough variety nor amount of content included...!
gameplay, graphics, guns , movement was great ,.... just not enough new stuff to warrant this being a sequel. then the DLC came out and was very disappointing in it's lack of added content , as well.
Along with the atrocious inability to make teams easily nor communicate with each other. Terrible , maybe the worst I've ever seen for a game that absolutely wanted to encourage endgame team content..!
