StarCraft 2

Been playing, watching and making videos for it ever since it came out in 2010.
It pretty much pioneered modern esports in the west and LoL, Dota, CS:Go and Fortnite then elevated it to another level.
Which pathed the way for all those GAAS titles.
While StarCraft did drop off in hype it is still going and still being updated and played all those years later.
