There's a production table in the OP now. (Thanks monty)
Still mostly incomplete, it should help you guys get started nonetheless.
The items missing from it are basically just ground vehicles, and the weapons to take on ground vehicles (with infantry.) Also airframes. It has all the essentials though, I'll add that fancy stuff asap. (just kind of a pain to edit the OP because its so ****in long)
Player list in the 2nd post is now fully operational.
Also:
Megacorps start with ships, obviously, and each ship needs 1 Atmospherics and .5 Ablatives per turn as its "upkeep." The civilian mass conveyors are the physical things that actually bring the tithes from colonies to and fro (you start with quite a few redundant ones), due to their constant movement, they are always consuming dark matter.
