This thread is mostly to take a look at the landscape of competitive games and how they evolve, if at all, over time. Going to keep the initial post (this one) fairly brief to hopefully invite some general discussion before getting into more specific conversation, if any.
I personally feel, despite their popularity, that First Person Shooters have now become the least evolved form of competitive gaming while fighting games and MOBAs, such as League of Legends, are the most evolving.
