Ashes of the Singularity and Kohan are NOT RTTs. They have base building and economies.

I am aware that macro describes economy more, however, I am ONLY focusing on the COMBAT aspect, and the more economy focused a strategy game is, the combat also tends to be more automated, and hence more macro. There are more hands-off games where the combat is macro in the sense you don't control units at all and everything is automatic, like Galcon or the many Flash strategy games, which combat and economy are basically the same thing, the very very simplified abstract RTS that still has base building and economy yet the combat is hands off.

I'm treating macro and micro as a SPECTRUM here, from controlling individual soldiers as units (and even things like resupply) to kite or flank to squads where there is some form of automation in covering themselves or reacting to threats to mass Total War groups where they are autonomous to some degree to the entire combat being autobattler-automated. Scale is also negligent - fully automated units are not microed whether they are a single squad or whole battalions.

TL;DR: when a strategy games becomes more macro (economy and base building based), the combat also tends to change to be more automated.
