@PiyozR (I was gonna post this on your profile, but it has a 420 character limit, and therefore, I have to be the thread necromancer to contribute this new idea.)
Sorry to bother you, but remember that MOBA-like "Calamari Turf War" segment on the conlang guide? I kind of want to elaborate more on its origin, but the forum post is dead (n.b.: this will have some real-world parallels with how the MOBA genre was formed, and because I am lazy to invent new terms, I just inserted the real figures' names and aliases, and used the game names of the equivalent formats, indicated in square brackets. Feel free to edit as necessary).
M.E.(Mollusk Era) 1989/12/15: The style is first introduced in Calamari County, in a primitive form (one can argue that this is the closest the format has been compared to the Turf Wars run in Inkopolis). This form was starkly different compared to the current iteration of the format. Among the differences were that there were no real "builds" present in this iteration as is current tradition in current formats. However, the "fight an enemy team's opposing units" and "game lasts until base is destroyed" concepts were presents.
M.E. 199?/??/??: A creator under the alias of [Aeon64] (nobody knows where he or she is from, or who he or she is. We can imply s/he's an Octoling or West Inkling, or possibly none of those species based on linguistic conventions) introduces his [Aeon of Strife] format. Introduces the "standard" map of 3 lanes and the "hero-centric" combat.
M.E. 2003/??/??: The Aeon of Strife format is refined further into the "Defense of the Ancients" format by creators [Eul], [Icefrog] (r.n. unknown), and [Guinsoo] (r.n. Steve Feak), located somewhere in [N. America.] This is the grandfather template by which all current schools of this style derive from, introducing the "towers" in the lanes between the base. The format is picked up by millions worldwide, but there was still no official regulation.
M.E. 2006/09/??: [Riot Games], the org that would eventually manage this format in a new form worldwide, is founded. [Guinsoo] leaves [Dota] management.
M.E. 2007/12/??: Infrastructure concerns among [DotA] format players worldwide (the management was intense and the resources required were absurd to even run such an event, with several people required to play the unsatisfactory "minion" role) nearly kill the physical format of the event. Small scale variants arise, more in the form of what gamers call a FPS. A solution had to be implemented.
M.E. 2009/10/27: The first iteration of the online PC game [League of Legends], the game to revive and preserve the format, is introduced by [Riot Games]. Eventually adopted throughout [NA] and [Europe].
M.E. 2010: The ranked ladder forms for the league. Confined to ladders per region, with a grand ladder measuring players worldwide. Pro teams eventually form in [NA] and [Europe].
M.E. 2010/10/??: First major tournament run, featuring teams for this game from around the world. A European team ends up as the victor.
M.E. 2013: Octo Valley (n.b.: I like to use them as a stand-in for Korea, both North and South) adopts the LoL format, and starts their ranked ladder. Historically, they had been playing the progenitor formats since their inception. Pro teams form in the South to compete in the [LoL Champions of Korea league], while the North still allocate physical resources to their take on the format (which is relatively confined to its home region).
M.E. 2013/09/??: Other variations on the format arise to compete with this LoL format. The most popular of these variations ends up being one by [IceFrog] and [Eul] of the DotA era.
M.E. 2014: Pro teams arise among Inkling circles. Ranked ladder forms. Made popular among retired Turf Warriors. Is especially welcomed in Calamari County, as the creators acknowledge the region's contribution to the current format.
M.E. 2015 The first season of the LoL Inkling League is run. Pro teams arise among other regions, henceforth known as "Wildcard regions." They eventually get added into the main lineup, with one team from these regions competing in the global competitive event.
M.E. 2016/10/22: The largest tournament in attendance and prize pool by far, [World Championship 2016], is run.
M.E. 2017: Healthy competition is maintained, and a healthy player economy arises. Changes in Turf War regulations (increasing license fees (n.b.: my way of explaining Nintendo's paid online multiplayer)) attract more to the game.
