Bloody Mess is supposed to simulate the effect of getting a lethal critical hit
I thought the fallout 1 & 2 versions was your enemy dying in the most gory way (the same as if a critical) even if you only just killed them.
Don't worry, once they start showing off NPC interactions, dialogue, quests, etc, the complaints will become more substantial.
So by that statement you are saying that you will look at every peace fallout 3 info, and then find stuff to back up your complaints, then you'll pirate it to see if its worth buying even thought you will most likely right it off before then due to the 'oblivion with guns'-ness?
