I had cut this out from the MAS building system because the extra variable made things even more complicated, but I had planned on introducing a currency system, so people could purchase additional weapons and parts as the RP goes on.

I plan on introducing this system after all, and the equipment will often weigh and cost less power than their standard counterparts (mainly to give incentive to change things up). As a non-military organization, I want this idea of continual customization and improvement by picking up and finding cool new parts and equipment to play a big part in this role play. And as we are a outfit motivated in part by money, it only makes sense that we'll be buying and trading. 

I'll be going over character sheets again momentarily and will assign you some arbitrary number of funds based on how advanced your machine is, how long your character has been working, etc.

That being said, equipment degradation will be a thing in this role play. If you're weapon gets cut in half (which chances are will happen to at least one of you) you wont just have it at the start of the next battle, you'll have to spend funds to repair or replace said weapon.
