So, what sort of regiments is everybody building and playing? Some bit of standard gear that you can't go without? A homeworld that stands above the rest?
Currently, we're playing a game as a Salvage Regiment with Sappers doctrine and an Introspective leader. EVERYONE has tech use, technomat, operate, foresight - and a plasma cutter. We solve problems. Not problems such as "what is beauty", for that would fall within your purviews of philosophy.
We have another game running on a different day of the week, it's going to end very soon. That one has been running mechanized, I would personally like to switch to drop troops.
