The problem is on the default setting, the game autosaves after every 15 min, saves on fast travel, traveling into new locations, as well as when you sleep or wait.
Now if you don't change this, then your going to have a problem, if you want to play several characters, become the save list will get extremley long.
This is what ive done. Disable autosaves, disable saving on fast travel, traveling, sleep/wait. So now the game won't save at all, unless i manually save.
Then make 3 save slots (if you have 2 characters, 3 per each). I believe 3 is a decant number.
You may think this actually hurts gameplay, since what if you forget to save, or save at the wrong moment?
To fix this issue, use common sense. For example before going into a dangerous area which you know is full of hostiles.....save at least on 1 save slot. Then when you go in use your other save slots while going through the area (keep switching back and forth on the 2 free slots). If anything goes wrong while saving in the dungeon, then you always have the save slot at the entrance.
These tips here are beneficial exspecially when there is more then 1 person in your family who share 1 xbox to play skyrim (even worse when say 2+ people each create more then 1 character).
Another tip, is when say your in a city, and you want to end for the day. Save on all 3 save slots (don't do this if your in danger, like being attacked by a dragon). That way, the name of the city would show on your save slot. This is helpful in remembering which save slot belongs to which character when you want to load/save a game.
For example, say i had a lizard and a nord, and i know my Argonian has never went to Solitude...while my Nord has. So if i look in the save list....i know the 3 slots that are called SOLITUDE are not for my Argonian. This is helpfull, because there is less of a chance of accidently overwritting a save.
To finish up, if you use these tactics of mine, everytime you start up you may have to check the settings again. For sometimes the settings that i changed get restarted back to default (this doesn't happen all the time), then you would have to change them again.
Hoped that help.
