My view on story mode:
When story mode is added , and you go to the nether and defeat a certain boss there , everything should start to shake , and some blocks would fall as if they were sand or gravel , tiny bits fall , the nether slowly collapses and you must get back to your portal , before everything collapses. At the horizon , there are nothing but ghasts , and the lava level in the nether slowly rises simulating the ground sinking in the lava.

http://www.youtube.com/watch?v=QhPHB6ovnKE] this music plays. When it says "Mojang Specifications" you see behind all of the ghasts at the horizon , a notch head rising to the point you can just see his head , but not his neck. The ghasts shoot him , but it has no effect. You hear a very loud sound and see Notch's better-than-diamond-ore eyes ligth up witb a light so bright , it burns everything in it's path. All the ghasts die , and you are temporarily blinded. The eyes shoot huge blue plasma beams after the chargeup that slowly solidify all lava. The notch head descends again , leaving you with a path to your portal. Once you get to the portal , a final ghast that hid himself comes and shoots out your portal , just before you are able to enter the portal. Your head fills with rage , your screen goes all 3D-overlay and you take your sword , make an epic leap from a high cliff over lava in slow motion to the ghast , land on his head , put your sword in the top of it , and ride it while it slowly spins down like a crashing helicopter. You see the nether spinning so fast around you , and spot an outhang somewhere next to the ghast. You wait till it is in the right position , and make an epic leap. Suddenly , the lava begins rising faster , and boiling hotter. The small lava projectiles become more and more , and they hit your portal frame because they fly so high , and because the lava rises. The portal is re-activated , and you jump trough in your final , epic move. Back at your world , there are 100 dark days of 24/7 night awaiting you. But you get the power. You feel in your pocket , just to see Notch has put a bit of his powerstones from his eyes in your pocket. You quickly make it into a sword , wich is infact capable of KILLING creepers even before they SPAWN. After these 100 days of constant fighting , at the horizon it isn't the sun rising , but it is Notch's head , killing all creepers with his lazer eyes. From that day on , Notch illuminates the night sky , and you can see bright lazers going from his eyes to nearby enemies. You have finally succeeded.
Yay I am lifeless.
