What RTS games are you referring to? I was under the impression that CoH2 was the most popular multiplayer RTS game after Starcraft 2.
That actually should've just said competitive games; but even if we're talking about RTS only, being behind SC is enough of an example if you look at how the SC community is healthy and active through ESL events while here at CoH2 we're busy praying this year's community-tested patches will come soon enough to keep at least some of the players from leaving and save the multiplayer from turning into a 15-minute queue time fest.
