Good idea, here are some random ideas:
- Storage is leased, because the game needs money sinks.
- Storage units are available both in stations and planetary bases. Planetary bases are much less expensive.
- Storage is local to the sation/base. You must dock there to have access to it.
- One storage unit holds 10t. 1000 materials weight 1t (just an example obviously).
- The lease is charged weekly, the credits are withdrawed directly from the user's account. The timer only runs when the player is in the game, to be fair to players who leave the game for long periods of time (imagine not playing for 6 months, and then returning to see your account with no credits at all).
- If the player runs out of credits, a warning message appears giving the player 48hs to pay the debt, or else the storage units get locked until payment is made.
- A storage transfer service is available, so you can move your storage units from one station/base to another, for a fee of course (we are going to be able to transfer ships, so why not storage too?).
- We should be able to store materials, commodities, modules and weapons (i.e. so we swap between engineer customized modules and guns)
Can't think of anything else right now... but that's a start.
