Which Stargrave supplements support solo play?

[Terry Deathstrike]

Hope Eternal, Dead or Alive and Quarantine 37 all have substantial rules and scenarios for solo play so they're on the list 

Are the other supplements also worth picking up? I believe Bold Endeavour has a single scenario that can be played solo. Do The Last Prospector and Death Vector have anything that can be integrated into a solo campaign?

I don't think there's a great amount beyond the three you first named but they're definitely plenty to be getting on with. I reckon if you played a game a week you'd need nearly a year to be done.

If you're a stickler for accurate terrain and foes then it's going to take you much longer.

Good point!

Probably best to start small with a few of the books and work my way through them

It's a Frostgrave book, but Perilous Dark has as much general solo scenario design advice as specific Frostgrave content.  And, of course, the Frostgrave and Stargrave bestiary entries are pretty much usable in both games.  Oh!  And Perilous Dark scenarios use Gnolls frequently, which rules-wise are just "bad guy" equivalents of the standard soldiers available for PC bands...so you could probably just swap in acceptable Stargrave soldier types for those scenarios.
