Games

edit

TheDotaseries includes four games that are centered around competitive,online multiplayergameplay. The original version,Defense of the Ancients,is a community-createdWarcraft IIIcustom map developed with theWarcraft III World Editorthat was first released in 2003.[1]The franchise name,"Dota",is derived from the original map's acronym,DotA.[2]Dota 2,its standalone installment, was released as a free-to-play sequel in July 2013.[3]The first spin-off, adigital collectible card gamecalledArtifact,was released in November 2018.[4]The second spin-off, anauto battlercalledDota Underlords,was released in February 2020.[5]

The main installments in the series aremultiplayer online battle arenagames, where the player assumes control over a single character - a "hero" - from a large roster of characters and coordinates with their teammates to destroy their opponents' large structure called an Ancient, while defending their own.[6]Unlike the original version, which is largely derived from the setting of theWarcraftseries, the standalone games share their own continuity.[2]Likewise, the standalone games utilize theSourcegame engine andSteamdistribution platform - both developed by Valve.[7]

Defense of the Ancients(DotA)

edit

The installment which established theDotaintellectual property was theWarcraft III: Reign of Chaoscustom mapDefense of the Ancients(DotA). Independently developed and released by the pseudonymous designer Eul in 2003, it was inspired byAeon of Strife,a multiplayerStarCraftmap.[8]Before everyDotAmatch, up to ten players are organized into two teams called the Scourge and the Sentinel—inspired by the factions fromWarcraftlore—with the former in the northeast corner and the latter in the southwest corner of a nearly-symmetrical map. Using one of several game modes, the players each choose a single powerful unit called a "hero", who they are granted control of throughout the match. Heroes maintain special tactical advantages, in the way of their statistics, attack, and damage types, as well as abilities that can be learned and enhanced through leveling up from combat. Team coordination and roster composition are considered crucial for a successful match.[9]The currency of the game is gold, which may be used for purchasing items that may enhance a hero's statistics and provide special abilities. Gold is awarded to players for destroying enemies and in increments on a rolling basis, while also being deducted for the death of one's hero.[10]Heroes battle alongside weaker computer-controlled infantry units periodically dispatched in waves, who traverse three paths called "lanes", which connect the Scourge and Sentinel bases.[11][12]Each lane is lined with defensive towers, which are not only more powerful the closer they are to their respective bases, but invulnerable until their predecessors are destroyed. At the center of each base is a central structure called an "Ancient", which is either the World Tree for the Sentinel or the Frozen Throne for the Scourge. To win a match, the enemy's Ancient must be destroyed.[12]

Dota 2

edit

Valve's interest in theDotaintellectual property began when several veteran employees, includingTeam Fortress 2designerRobin Walkerand executive Erik Johnson, became fans of the map and wanted to build a modern sequel.[13]The company corresponded with IceFrog by email about his long-term plans for the project,[14]and he was subsequently hired to direct a sequel.[15]IceFrog first announced his new position through his blog in October 2009,[16]withDota 2being officially announced a year later.[17]Shortly after, Valve filed a trademark claim for theDotaname.[18]AtGamescom2011, company presidentGabe Newellexplained that thetrademarkwas needed to develop a sequel with the already-identifiable brand.[19]Holding theDotaname to be a community asset, Feak and Mescon filed an opposing trademark forDotaon behalf of DotA-Allstars, LLC (then a subsidiary ofRiot Games) in August 2010.[20]Rob Pardo,theexecutive vice presidentof Blizzard Entertainment at the time, similarly stated that theDotaname belonged to the mod's community. Blizzard acquired DotA-Allstars, LLC from Riot Games and filed an opposition against Valve in November 2011, citing Blizzard's ownership of both theWarcraft III World Editorand DotA-Allstars, LLC as proper claims to the franchise name.[21]The dispute was settled in May 2012, with Valve retaining commercial rights to theDotatrademark, while allowing non-commercial use of the name by third-parties.[22]

An early goal of theDota 2team was the adaptation ofDefense of the Ancients'saesthetic style for theSource engine.[17]The Radiant and Dire factions replaced theSentinelandScourgefrom the map, respectively. Character names, abilities, items, and map design from the map were largely retained, with some changes due to trademarks owned by Blizzard. In the first Q&A session regardingDota 2,IceFrog explained that the game would build upon the map without making significant changes to its core.[15]Valve contracted major contributors from theDefense of the Ancientscommunity, including Eul and artist Kendrick Lim, to assist with the sequel.[23]Following nearly two years of beta testing,Dota 2was officially released onSteamfor Windows on July 9, 2013, and forOS XandLinuxon July 18, 2013.[24][25][26]The game did not launch with every hero fromDefense of the Ancients.Instead, the missing ones were added in various post-release updates, with the final one, as well as the firstDota 2original hero, being added in 2016.[27][28]Since its release,Dota 2has been cited as one of thegreatest video games of all time.[29][30][31][32]It is also the most lucrative esports game of all time, earning teams and players a total of overUS$100 million by June 2017.[33]
