I'm probably about half-way done building the ships tree. None of the theory techs I've made have names or descriptions yet, and most applications and ship parts have very basic/placeholder descriptions.
The ships tree is more or less divided into two separate tree structures at the moment: the hull tree and the everything else tree. I do not have plans to make interdependencies between them at this point.
The hull tree has four theories dependant on each other trunk-style, small medium, large and huge hulls, each of which (if that's OK) unlocks/will unlock a shipyard building required for making hulls of that size. Then there are applications branching from different shapes of hull - Standard (the ones that were there before), Internal (only internal slots, slightly fewer total slots), Combat (only external slots, more total slots than standard) and Bulky (same slots and almost as much health as standard hull of the next level, but slower and almost as expensive as standard hull of the next level).
This is totally open to revision of course, and in the future, more creative hull shapes might be added? Also, empty hull is now a type of small hull.
The everything else tree has, at the moment, 6 theories, dependent on each other trunk-style, 5 of which are filled out with applications, only the original 3 of which actually have names. Ships is by far the most application-rich tree, with 6 applications per theory. Also, since there is only one theory per tech level, the RP costs will eventually be more gradual than for the other trees. There are two weapons, two other ship parts, one planetary defense/shield app, and one totally random app per tech level. I have renamed Optical Sensors to Optical Scanner, since I'm saving the rather esoteric and uninformative (on its own, anyway) term "Sensors" for the highest level of detection equipment. I am also considering the possibility of detection parts (or other parts) automatically giving bonuses to planet detection (or the relevant meter).
Josh's mass driver icon is also in use.
