What has MGS4 added compared to the last game? Graphics, online, new storyline, (???)
What has brawl added? Graphics compared to cube, online, a one player or co-op story mode, new characters, four new ways of control, rotation mode, and just about everything at smashbros.com
Besides, I meant why is the hype around the fact that the game will sell systems, I know this is true but so many people seem to think it will boost sales incredibly.
