I always thought those strategy games were missing a competitive community and better PvP experience but I could also see how more replayability would make them more popular.
I think it's hard to make those PvP modes compelling to most people, being turn-based with longer turns is rough (card games get away with it because turns are typically pretty short).
It's hard to think of popular turn-based video games where it's popular for multiplayer and the turns are long.
