No I mean Missions that tell a Story, like the Foundry missions do. The Cluster Missions are nce, but they do not tell a story AND they do not reward enough.
You can't have meaningful story -and- limitless exploration at the same time. Someone has to write those things and eventually you'll run out even if you have a whole team doing nothing but that day in and day out; the old axiom of 'months to make, hours to run' is the big limiter.
The Exploration missions are a good try at getting some of that but they belong to an older period of the game and aren't quite in step anymore. It needs a bit of a refurbishing and some more polish.
