The game titles with use synonyms of parts of the title or word plays on the name.
Example: Spiderman ---> Arachnid Guy
I got this idea from the user Overtired and his quiz

This seems more like a "Video Games by Synonym" than the method that Overtired used. His matched the first letters of each word. Mortal Kombat would be something like Murderous Knockout.
I only realized he matched the first letters half-way into making this. Also, I only got the idea from him. Regardless, in the description, I said it was based on synonyms.
