Thanks for your insight...
I am thinking about "enhancing" the standard passenger ferrying a bit... without really changing the missions. Here are some ideas (to get your input mostly)...
- Equipment which enhances the standard berths (entertainment systems; massage beds and similar things). May increase the fee via a pay-per-use system.
- Tips by passengers for a nice flight (no enemy encounters) or maybe for a good fight (keeping the passenger always in a safe state, that is) depending on the passenger. Passenger may or may not hint about preferences. Absolutely not meeting a passenger's needs may even decrease your passenger ferrying reputation a tiny bit.
- Passenger may use the TeaMaker and leave a tip (maybe also additional equipment) or get angry if there is no Tea available or (worst case) your TeaMaker is out of supplies.
- Additional equipment like Spa/Sauna, Medbay... which increases the fee significantly (pay-per-use, needs TCs)
- Passengers may interrupt you, maybe during uninteresting flights, for a quick chat.
- Passengers may have fun (or not - allergies?) with your Ship's cats, with Trumbles... or they may even forget a Trumble or two on your ship? Or they could by one...
- Passengers who need several berths (for butlers and own security staff).
- Passengers may meet and have fun or get into arguments, increasing/decreasing your tip. Maybe you even need to lock their berths

- Crew (you need to hire them, they cost per game time) for the people's entertainment/security in pay-per-use. Passenger may get angry if they can't get the massage they need NOW because your crew is just now working at someone else's back.
