Confused why Middle-Earth: Shadow of Mordor left "Lord of the Rings" out of its name? Well, lead designer Bob Roberts just explained to Eurogamer that the omission was a deliberate choice to make sure the game was seen as "clearly its own thing" by keeping it "separate" from established LOTR franchises. Mystery solved!
Well, if they wanted it to be its own thing, why base the Gollum character model off the movies' Gollum and why get a voice actor that sounds just like Andy Serkis. In fact, why even have Gollum in it to begin with? It was a bit forced and felt like it was done purposely to connect it to the movie world.
