I'd forgotten about the Rat.
Seemed pretty unusual to rest what I imagined was a top-tier (even if a relatively new import) for a year, and have one of your top droids working on a WW2 vampire story, (an odd fit for 2000AD) + disposable tharg stories etc.
I guess it could have been the scripts weren't ready.
What's weird is that Stainless Steel Rat is well-liked, and Rick Random isn't much, despite them both originating from Harry Harrison.
I guess the Rat is much more fun, and feels less retro?
