First three ships that will be in game, of three different classes. Shipline codename "Phoenix". Currently pondering their sizes so that one could fit another inside. A draft classification of types is further in the thread.
1. Small vessels: STL, meant for near-orbit operation (say, within 1 AU),
can combat, can harvest asteroids, etc. Small and maneuverable.
Cheap. Consumes reasonably small amount of fuel, so it doesn't require player to grind for it.
2. Medium vessel: FTL (10-100c less or more, should cross planetary
system in about 10 minutes). Meant for interplanetary travel, serves as a
small base of operation, can carry small vessels (maybe 1-2), not meant
for combat or anything else other than traveling and hauling.
3. Large vessel: same as medium, but bigger, travels faster (around
1000-10000c, or whichever is needed to travel between nearby stars within
10-minute timeframe, for the sake of gameplay). Same as medium vessel, but can store and carry even more.
Probably, they will have some other unique traits and purposes, but it is too early to ponder those right now.
Trying to fit em in. Also I think I will not go for an outside fixture for ships, because docking bays look better with the hull design, and there will be no need to strictly monitor ship bounding boxes.
