While I agree that the entire premise of this DLC just feels wrong, I will probably play it anyway. Judging from the screenshots, at least Bethesda takes this DLC very seriously and confess it actually looks great. The graphics that is, cannot say anything about the gameplay for now. Part of me feels that this is a showcase of what their engine can do. Those screenshots looks so different than F3 that if one didn't knew it was F3 one wouldn't be able to tell. It looks exactly like a modern engine space first-person shooter to me.
Interestingly, there will be nothing left for me after finishing this DLC, so the weapons you find aren't that interesting to me. The only DLC that actually allows you to play with your "awesome loot" and your companions, is Broken Steel.
