I was poking around the Paizo website, and noticed that there are minis for Pathfinder, and others for Pathfinder Chronicles. What's the difference between the two? I couldn't see anything in my research.
They try to explain the various product lines on the Paizo Pathfinder family page here. Pathfinder Chronicles is actually a deprecated name, it's now called Pathfinder Campaign Setting for clarity.
A lot of this was somewhat confusing and has undergone a couple revs of rebranding, so when you see "Pathfinder Chronicles Mini" it probably is just a legacy term from before there was a "Pathfinder Minis" line and they were lumped into Chronicles.
