I can see the potential problem of the full game running out of new things to do very quickly. Which is why it is a shame that the developers are playing it too safe by limiting PVP and most non-party player interactions to the Dark Zones. Like with Destiny, the content in this game will be limited by budgets, development time and hard drive space requirements, which is why it is a shame that they haven't given more tools for the players to really make the game world more interesting. It seems like a neutered version of the original Division pitch which they sold to me. PVE zones are not that interesting after you have seen all the repetitive AI encounters 20+ times and you realise that you are mainly farming for more spinmetal.
I will buy it because it is another co-op game to play on Xbox One, but I don't think that the game itself is anything groundbreaking. It feels like a compromise, trying to please everyone.
