Seems as if you generalized this to suit yourself, and not the community:
To me, your list of suggestions is more of a list containing your opinions about different aspects of the game. Just because you feel this way about, say, the bow, or fighting mobs, doesn't necessarily mean others are going to feel this way as well.
And I, frankly, enjoy Minecraft the way it is now ^.^
This whole idea is ridiculous man, admit it, you just hate the hunger-bar. I think this is an idea of yours that removes all the things you don't like and include all the things that were in the old Beta, why bother if you've an Xbox version just downgrade it. This is just another pointless mod idea.Again I'll say: NO-SUPPORT!
I agree with most of the responses here. This suggestion seems like it would fit much better as a mod and not a new gamemode for the game. There is an easy way to rectify this though; you can set your FOV to 'Quake Pro' which would make it seem like you're running faster, and then just set the difficulty to hard or hardcore. That's actually a decent idea for a SSP challenge...
