Yeah, I really enjoyed that in single player. Long range artillery, sensors, good automation of units, interesting naval combat. I did not like the later games in the series, because they tended to encourage you to zoom out all the way and I was just staring at a bunch of unit icons.

If you're not familiar with it, there is an open-source implementation of the TA engine (Spring RTS), and some games that were built on it; you may enjoy Zero-K.
