In fable III, you can have more than one save game. So many forums I have come to and people don't know this, so I thought I would post it here.
1. Go to the 'Options' panel in the sanctuary.
2. Press the first option, 'Game management,' as if you are going to save the game.
3. Press 'Load.' Many don't actually think that this means you can have multiple saves. It's really wierd =/

Games on Demand

You can buy Games on Demand with Microsoft points; but they are REAL expensive. When you find the game you would like to buy- and have the good few thousand in your account- press buy on the game in the GoD marketplace and then (X). It will show the new cost and amount you have in Microsoft points.

That is it! Two simple things.
