So you want a half done story? You sound like a little child obsessed with shooting things. A space shooter? Yeah that shows the true capability of the system, not really.
Actually I'm 26 and I read books more often than I play video games. If I want a good story, I'll read a book. If I want to play a video game, let me enjoy the GAME without dealing with what will probably be a worthless story anyway. Super Mario never has a story beyond rescuing the Princess and getting a cake, what's the difference?
The stories of games are most usually godawful and would be better off not existing at all. A simple story that sets up the role playing aspect is all you need and any more than that is usually more than they can write without messing up.
Old Zelda, Mario, Starfox64, Phantasy Star Online, Ikaruga, to name a few off the top of my head, got it right. The last time Nintendo tried in earnest with a real story, we got Twilight Princess, and it just made me laugh.
Even better example. What would "show the capability of the system" better, a game with a simple concept like Sonic Generations, or the convoluted storytelling mess of Sonic Adventure 2?
