Hello everyone, I would just like to provide some food for thought based on an idea someone posted in another forum for the old SPI WotR game.
It should be possible for the FP to continue playing after a Shadow corruption victory, hoping to achieve a Draw. This could be accomplished either by the FP achieving a Military Victory, or by a Ring-like "quest": The Plea to Valinor, which would consist in sending a Fellow or a Leader by ship to request the help of the Valar. The odds for this should be quite daunting, of course.
Once Sauron gets the Ring, he should be able to be mustered as a Level 4 Character (the word Minion seems quite inappropriate!). Also Eye Action Dice would turn into "Will of Sauron" Action Dice, acting as Shadow jokers like FP WotW dice.
I will try to elaborate more on this. Comments welcome!
