We might as well start with Dota 2, considering it still maintains the biggest e-sports prize on the planet: the International 5 featured a prize pool of $18 million this year. It’s huge. Dota 2 is a successor to the WarCraft III mod DOTA, or Defense of the Ancients, the godfather of the now-booming Multiplayer online battle arena (MOBA) genre. Players pick a hero and battle it out against the other team, competing to bring down the enemy base by outmanoeuvring foes with skilful tactics. Or, if you’re like us, you pick a hero and mess something up five minutes in and your entire team gets angry because they know you just lost them the game.
