Cargo events: their purpose?

[SpaceTime]

These events aim in creating activity in specific places/routes. Obviously this means that the more wide and spread the route is, the less the effect. Number 2) tries to incorporate as many places and factions as possible but that ultimately fails to create specific activity or any boosted activity for that matter.

An ore or non-ore commodity along with a contraband is the best combination in my opinion. It makes the route small and simple. It only requires some fine-tuning in order to avoid some bad situations with the contraband selling/buying points and of course I also like on a personal level for the trade route to make sense in-roleplay.
