All rules and components are in both English and French.
The easiest way to see all of the content with pictures of miniatures is to look on boardgamegeek website, search for Conan (2016). Under images and also under expansions (everything from 2016-2021).
Most minis are not painted. Some are primed, a few are partly painted and a few are finished. There was an attempt to strip the bad primer off half the pirate minis, which turned them green and was never finished. They are still useable and paintable, they just don't look great right now.
The foam inserts in the 2 base game boxes causes the lids to not fit flush, so the boxes are thicker than without the foam.
Most of the character sheets are sleeved.
Also available for sale are Mythic Battles Pantheon and Ragnarök, which have some compatible components with Conan.
