main remaining gameplay features

• patrols for contraband

  • fines when getting caught

• purchase upgrades (cargo, slower scan time, show buy/sell in portal?)

  • cargo limits
  • upgrades actually do stuff

• flavor

  • world descriptions
  • news system
  • plot events

• cargo

  • high/low indicator
  • every world that sells a good also buys it
  • almost every good should be able to be sold almost anywhere

• nice-to-haves:

  • autopilot
  • import warnings on portals
  • bad ending
  • portals you can't enter (make the world seem bigger?) (actually this is probably just confusing as long as we have travelpass)
  • add further indicators to portals that they're... different... particles?

plot progression

• go around buying and selling
• find yapian, realize it's way more profitable
• trade it a bunch
• [news] EIC declares war on the empire
• patrols start chasing you for yapian
• [news] empire fighting the effects of yapian

at this point the player can decide to continue trading yapian, which causes patrols to become much more aggressive; if you continue trading it, you'll end up getting your ass kicked.

• [news] war is going badly for empire
• weapons start to become buyable in EIC ports
• [news] EIC seizes freshharbor

make enough weapons deliveries to Empire ports to trigger winning: roll the credits, maybe a little blurb about the real historical events
