I've been reading & enjoying this thread, but I have to admit that the casual comments about slaughtering Orcs & awarding Shadow Points concern me as well. IMHO, this isn't quite what Tolkien was all about & seems to depart somewhat from the themes of
ToR.
That aside, however, Mordor is an intriguing setting for an adventure or two, & one alternative for an LM is to set the time frame before or after the War of the Ring. That way, your heroes have at least a chance to survive.
For example, my own game played through the War, so the next company I run will begin when Sauron falls. While this deletes him (& the Nazgûl) from the story, it's surprising how many foes may have escaped to challenge your heroes.
The Mouth of Sauron rides back to the Black Gate, but there is no further mention, so he may live.
The text actually mentions that Shelob may survive - the Hobbits who later write the
Red Book of Westmarch simply don't know
.
Gothmog only receives a couple of quick lines. Who is he (I make him a Variag sorcerer instead of a Half-troll, as MERP did, or not one of the Nazgûl, as SPI did)? At any rate, he vanishes from the tale.
Even Shagrat may survive. Tolkien's chronology at Marquette mentions that he is put to death when he reaches the Dark Tower, but in the published
LotR he just reaches the tower.
So, what to do with all of these great villains? Well, Elessar frees the slaves, but then what? How easily do they throw off the yoke of thralldom against the hordes of servants of the Enemy, demoralized by their master's fall or otherwise? If only the King had some heroes to investigate Mordor, & perhaps organize/lead the slaves to gain their freedom. It's a stretch from the books, but it works for a game
