In the Springs, Stephan and Forrest have Aquans. Adam and Rob have Terrans. Marty and John have Dindrenzi. Dave has Directorate, but I haven't seen him play in a while. Jason S. has Relthoza, not sure for Jason M. Troy has Directorate, but only core.
And eventually, I'll build Directorate, but that's WAY off.
And I'm trying to talk Scott maybe into buying my Aquan fleet and Aquan core helix.
Overall, I think Directorate or Sorylian are the lightest represented in regular play.
Maybe take a look at the matching ships for Firestorm too, realizing you'll eventually give in :-)
Is there a style of play you prefer?
