With a disclaimer that I have previously written a TF chronology and have a stronger interest in this than others...

On a second look at the Primal Scream volumne I realised that only three volumes into this series the reading order is already questionable. "Cold Comfort and Joy" (UK198) needs to come before "Time Wars" (UK199-205) partly because one of the characters in this story doesn't survive Time Wars!

Looking at some listings for upcoming volumes, they suggest they are putting "The Man in the Machine" (US51/UK211-212) in the same book as "Space Pirates" (UK180-187)... so when reading in order we'll see Fort Max quit after the devastating battles of Time Wars and the Underbase Saga before he's been in either!

Swap the two stories around (Man in the Machine in Primal Scream, Cold Comfort and Joy in Space Pirates (with the Firebug story) and all would be well.
