> you're expected to be controlling essentially every unit on the map at all times.
I think that's the core of a big criticism of Starcraft. After a certain point, it almost becomes a rhythm game.
The actual depth of the units was also smaller, compared to the fairly rich dynamics of TA.
This doesn't make it a worse game, but it is distinctly different.
Queuing orders in TA and then in Supreme Commanders was best-in-class. Both single units and structures, and groups of them (selected with an assignable hotkey), could have infinitely long command queues. Patrol mode was useful for both engineers and normal units. SupCom added air- and sea-based transportation corridors. The queues were not broken if you ran out of resources temporarily; they just paused and then resumed when possible. I played TA before StarCraft and after Warcraft 2 - I felt SC to be a huge downgrade in terms of controls, and dropped it almost immediately. SupCom then came close to the absolute peak of RTS for me in terms of controls, physics, and economy management. The problem with all the fan-made successors is that I don't want PvP at all, and they seem to focus on that, while the original TA and SupCom were incredible single-player experiences, too.
