Scholar I may be, but such things are always of interest to me. I treat all new Tolkien related media the same; with open-mindedness (as any scholar should), whether it be new editions of the novels, critical analysis from within the community, films, drama, music, art and videogames too.
I always remind my peers in the scholarly community of the following words of Tolkien:
"I would draw some of the great tales in fullness, and leave many only placed in the scheme, and sketched. The cycles should be linked to a majestic whole, and yet leave scope for other minds and hands wielding paint and music and drama."
Are the writers at Monolith wrong for injecting their own ideas into the mythos? Or are they taking heed of Tolkien's words to future generations? I lean to the latter in such matters. Of course the manner in which people add to the mythos and the merits of these additions should be scrutinized and analysed.
