I love these sorts of games; recently, I've been playing a lot of Wargame Airland Battle and Red Dragon but they're not what you're searching for.
If you want a RTS that has base building, resource gathering, tech updates etc, then you can either get something recent such as Age of Empire II HD or Red Alert 3, or just go ahead and find one of the old games from the golden age of the genre, such as Total Annihilation, AoE II, Empire Earth, Rise of Nations or the earlier C&C franchise games. You'd be surprised by the size of the active playerbase even when 2019's ten days away.
