I have never played Sins online, and Im not sure if I will now but, a few people at my college play and we are starting to LAN game it, we are all fairly new.
I have the most experience with TEC so Im running with em.
Right now my general strategy is to
Expand fast, with some frigates and colony ships + good ol Marza.
Tech up maintaining only enough millitary to expand quickly
Rush for a stable trade port\refinery economy, making sure all new colonies are upgraded with populace to minimize credit waste.
Where im shaky right now is with the very early buildings. I build refineries then capital factory, then a civil research facility. From there my build order changes and is generally sloppy.
So whats a good opening build order for TEC, what civic\millitary techs to I need ASAP? Trade ports and LRM frigates?
