I take it you've never heard of cut-scenes??
you mean the 30 sec vids that although are very kewl, will prolly be skipped after you watch them 20 times
you'll spend the majority of your time looking at you gun while you are playing the game and it'd just be nice to customize it without having to get a pre-order bonus
its not a big deal and im sure if ppl want it that bad they can add it later
Why? I say Why Not?
