As someone who thinks that ties are one the worst abominations of this world, I really don't understand why MS are being ridiculed for NOT wearing them.
I mean, seriously, what are the point of ties? If they had pockets, maybe, but as it is, they're useless little flaps of cloth dangling from your throat. Utter Bollocks.
Personally, I don't think anyone should be dressing up at all for these types of things. We're not showing off the merging of two bank dynasties, we're showing off flipping video games! Put on a comfortable T-shirt, some cargo pants, and be done with it.
That leads into another problem I have with these shows...It's always some nob that knows absolutely nothing about games, nor cares about them, that ends up showing them off! Instead of the developers themselves doing it. But that's another issue entirely...
