So, which upcoming RTS are you looking for?
I had access to some early builds of Stormgate, Zerospace and Battle Aces and also played the Tempest Rising demo.
And honestly, none of those seems like a proper "replacement" for StarCraft 2 for me.
Zerospace is still too early in development and I am not fan of hero units.
Stormgate has "camps" like some MOBA game, which I am not a fan of either, but it's mechanically the closest to SC2.
Battle Aces have simplified almost everything to the point of it being almost an idle clicker with only micro from time to time being required (and having systems that actually get in the way of microing lol). Still the 10 minute limit and ease of getting into may cause it to become quite popular. No macro, no scouting, just two keys to spam units and move them across the map and react to game telling you if enemy is teching or expanding.
And then there's the Tempest Rising that looks cool, sounds cool and may scratch that C&C itch. Still, it's not SC2, a different breed of classic RTS.
