there doesn't have to be another RTS for people to go play. at this point i only play coh2 with friends and spend the rest of my time on other games. i wish there was a good RTS option right now but i don't really like any of the available ones for one reason or another.
RTS games are dead.
There are games (game) like SC which are, at least for me, very boring.
There are games like Blitzkrieg/CoH which keep playerbase not becasue they are awesome but because they are about WW2.
I took a break form CoH2 and switched to other games but not RTS becasue there are none.
But when I look back, my god...
Cossacks 1, Battle for Middle earth, Warlord Battlecry III, Age of Empires.
Damn awesome RTS.
Yet currently, 15 years after Cossacks 1, we don't have ANY rts which would be so huge and complicated like cossakcs 1.
