After its release in 2010, StarCraft II competitors slowly replaced the prior Brood War competitions. For instance, StarCraft II has replaced the original video game in the WCG, and the originally Brood War-focused Proleague blended StarCraft II into their competitors, before lastly phasing out Brood War completely.
