I don't think we need to worry about lore unfriendly given all the options they have, before they get there.
We could have ads/banners for:
- The Shipyard who dont have ads yet
- The Minor Faction Controlling the Station
- The Power Controlling the System - need only be their symbol
- The Federal Navy wants you
- Join the Imperial Navy, see the Stars
- Ads for various rare goods.
- The various Super Corps mentioned in the System Description, they already have tag lines even.
Yes a low priority, but keep them simple, and they would add a lot of life to the game
Minor Factions having particular tag lines based on their Government Type
Vote the Lugh Party for Equality
vs
Hail the Order of Mudhrid
vs
Long live the Revolution
The People Eranin Party
The Super Corps could be grouped by Economy type that produces the good they sell, so their ads could be seen at stations that match the economy type.
Ads for Rare goods outside the stations that sell them.
Outside a High Tech station is an ad for Draftworks Incorporated "To the Limit and Beyond" [check Epsilon Hydri]
Outside a Industrial station that legally sells Personal Weapons an ad for Callaghan Firearms corporation (see LTT 911) or Blitz Weapon Stores "All calibres, all power ratings, one store!" (see Myrbat)
