keep em coming, I say.
With the notable exception of Death Planet, I've enjoyed reading them. Things which I never enjoyed at the time are so much better collected (Gibbons Rogue?), and often if its one character their collected tales mean we can follow their development: Ratfink, especially when it links to stories in the megazine.
I do think the Rebellion is missing a trick by facing these inward when they are bagged, face out would mean punters could see what the bonus was, might hook in a couple o waverers.
