I hope that chained missions become more complex, more than just a linear set of missions, but something that involves a choice of outcomes.
I'd like to see more of a point to being allied with a faction, also some point to being hostile. A persistent NPC nemesis, that generates when when you become hostile with a faction, would be great.
Depends on your definition of "linear". I don't mind if the game selects the next follow-on in a mission chain for me. I just want to be sure that there is a decent sized pool of follow-ons from which the game can select-if that makes sense.
For example, Assassination Missions currently only seem to be followed on by another Assassination Mission, whereas I could see ample justification for them to be followed on by a Courier Mission (excellent, please take this data to inform of the elimination of <$target_name>), or a Haulage/Passenger Mission (with the elimination of <$target_name>, it is now safe to transport <$cargo_name>/<$passenger_type>), or a massacre mission (the assassination of <$target_name> looks likely to spark retribution from their faction; in order to minimise that chance, we need you to eliminate X ships belonging to <$faction_name>). The game would then select one of those 5 options for you.....most possibly weighted by the current Faction State.
Salvage Missions should be able to trigger at least 3-4 different follow-on types, dependent on the kind of salvage you collected.
Passenger missions should be able to trigger one of several types of follow-on missions-such as Data Courier (The scientist who requires data to be brought to their new location to complete their work, or who wants you to take their data to <$station_name>), Bulk Passenger Missions (The Chief Scientist wants you to bring his X scientists to <$station_name> to help with his research), or haulage mission (The Scientist requires you to bring X units of <$commodity_name> to the station, to assist their research). Rebels, Rich Tourists, Criminals, Generals & CEO's might have their own set of follow-on missions......or the same types, but with more passenger specific flavours-just as they currently have their own set of wrinkles (though that too can be greatly expanded on).
Data Missions, in particular, are wide open to being able to trigger almost *any* follow-on mission, in a justifiable fashion-Passenger Missions, Haulage Missions, Surface Scan Missions, assassination missions, massacre missions....etc.
