Every so often, I Google "Maimed God's Saga" and even still "Saleron's Gambit" just to see what, if anything, is being said about them. My last search produced this link to the TV Tropes and Idioms page Nemorem recently mentioned. Scroll down to the video games portion to see that someone felt compelled to add TMGS to the page for the Scooby Doo Hoax... except that they then say it really doesn't fit at all.
For those who care, the Scooby Doo Hoax is when an area with purported supernatural activity is eventually found to be rife with earthly criminal activity that is using the supernatural legends as a mask to hide the criminals' true nature. I can see how a player may initially think that's what will be revealed in Navatranaasu, but no, that's not the truth behind the town's mystery.
Now, there are tropes galore in TMGS... How about The Treacherous Quest Giver? How about the Well Intentioned Extremist? I could probably find a hundred that fit.
