Thats what I have always loved about these games. Your strat is totaly different to mine.
As a note, I don't play against other people, just skirmish or 2 person coop against as many AI as we can manage. I fully expect to get pummeled if I played this way against humans
I focus on the tech tree, and aim to have my first experimental rolling off the fully resourced base within the 10-15 minute mark.
My starting order is 1 mass extractor and 2 power generators with an air factory along the line created. I then grab the next nearest mass point and then set my commander to put a 3rd power gen on the last point along the factories wall, and then queued to complete 4 power along a second wall. I also queue 2-3 tech one constructors so they start coming out as soon as the factory is completed. I also queue 1-2 fighters for defense, and then queue a tech 2 upgrade for the building, and then tech 2 engineers.
My first constructor normally completes at the same time I finish my 3rd power plant (depending on if the commander had to walk to the mass point or could reach from where he stood). I use these constructors to go put down extractors on all other mass points. I will also build a hydro plant if there is a gas point available, but normally have enough power without one anyway. I also will use any constructors that finish their queue early to build a few mass storage adjacent to the mass extractors.
Once I get my t2 engineers I start on a t2 power plant and get that up and running as quick as I can. I also watch and time my upgrade of my first mass extractor to t2. This requires the most judgement to avoid resource hell with the -10mass, -60 energy requirement for the upgrade. Once you get one done it is easier to have the resources to upgrade others as well as expanding the number of construction jobs you can do.
I also start placing down t2 defenses at choke points etc that my planes have found, and replace any lost air units. I normally have only about 2-5 fighters and 2-3 gunships before I start upgrading to my t3 factory.
T3 focuses on getting my first fusion reactor, followed by a mass fab, and other engineers work simultaniously on t3 sams, shields, and other defenses around my core.
In the campaign, I had no difficulty using this strategy, but will have to try it in a skirmish tonight and see if anything has changed.
