as said befor there will be a new ageing system where you age along with plot developmnts in the story (as apposed to, aging as you spend experience), so it should be alot more controlled as in you age normally.
not to sure about the pies thing, but i know what your talking about. im sure they would hav fixed little problems like that before they even brought to the table all the other ways of customizing your hero eg dyeing clothes.
you wont die as such in fable 2, what will happen is you will be knocked out and you can choose to spend experience or money to revive ( i have a sneaking suspicion that this has been changed as the testers simply turned off the console instead of losing experience) might have to chek this one out.
scaring is probably more prevelant as it affects the way people look at you moree so than it did in fable 1 in bloodstone you will be respected while in bowerstone you will be shunned.
and last but not least combat has had a huge revamp. it has bcome harder with the use of the one button system, and if you mix your attacks eg knock a bandit into the air then shoot him and then while he tries to get up blast him off a cliff with force push, in short combat multipliers. the more you mix it up the more experience you get.
wow thats a long post hope iv helped a little and if i got anything wrong (which i inevitably did)

please correct me.
