I'm currently running the Darkstryder Campaign and I had concern. I don't recall reading an official number of proton torpedoes carried by the FarStar. Any suggestions for a good number? I'm going for a count big enough to get the players through the official campaign without running out. But small enough they aren't tempted to resolve every space encounter with a torpedo barrage. I suppose I could just declare them out one day, but I'd rather not have to suddenly shoehorn in an adventure to acquire more, and would instead be able to just wait till they run low and make the acquisition more organic, if it's even necessary....

For those unfamiliar, the campaign follows the crew of a modified New Republic corvette (with a small fighter contingent) as it pursues an Imperial Moff deep into not-so-charted space out in the far rim. It has about 16 official adventures, with enough gaps the GM is required to fill that the total adventure count will likely be around 20-25 with a large multi-session conclusion. Of the official adventures I count roughly 11 (including the finale) that will have space battles, and two of those involve precision torpedo hits (space battles 8 and 9 IIRC)

Limited resources is a campaign theme, with several adventures based heavily around getting food, replacement parts, and good navigational data. So I feel ammo should be a concern, at least when we start talking Proton torpedoes....

Standard photon torpedo complement looks to be around 7 or 8. It might not be a bad idea to start with something like 10-15, then allow them to salvage more over the course of the campaign. You could also give them a few 'specially modified' torpedoes that have a chance of failure or are a plot-specific item.

Enough for plot

you really want to keep track of every ration bar, medpack, stim, Duterium, and raw materials?

Not all of the adventure has to happen in session. A lot of it can happen off camera. A quick roll on the rarity table and you can say "Looks like you are down to one reload after dealing with protecting that colony ship from asteroids a few weeks ago"
