My advice would be too have several created characters to experiment with taking your time too enjoy everything available in the game, each with different play styles to suit your own choices of the moment making the most of the 81 available perks to use in the main game and dlc.
I have lost count how many times I have created a new character in Skyrim alone, been through bleak falls barrow that many times I may as well take up residence lol
It obviously means you do have the opportunity to replay the quests you may have enjoyed the most in the past, some will like doing this knowing what to expect, others may find this boring and wish new challenges with the characters they have already created
Also the time you have available to play and the speed of which you play the game could be a deciding factor, personally I like to take my time and use a stealthy approach when entering new areas, common sense too me, others prefer to go rushing in hammer swinging ect
Once you arrive at level 50 for some reason levelling up takes eons to reach level 81 (not more about the level itself but really making use of the total amount of useful perks available collectively), I hope that information is not classed as a spoiler if so my apologies
Id rather take a fully completed level 81 female dumner conjuration vampire into the dragon born dlc on the 04/12/12 than my partly built level 10 breton warrior any given day of the week in all honesty, she is more versatile and ready for anything the dlc can throw my way and was created imo by a genius (credit goes to Skyrimadventuresforcrom-Youtube)
Either way I am sure we will all enjoy most things Bethesda offer too us when it arrives
