What I found helpful is that the languages have been separated in different booklets.
There is nothing more annoying than having to leaf through a big 30-page rulebook containing 4-5 different languages.
As for Prehistories, the game comes with 2 rulebooks, one in French, the other in English.
The rules of the game fit in only 8 pages! If we ignore the description of the objective cards and the setting up, we can even say that the explanation of the game fits in 4 pages.
The whole set of explanations is well organized, the examples are very clear. At a glance, we understand how the actions available to us actually work.
Many notes in yellow boxes provide a little more clarity, and a better understanding of the examples.
In addition, we have 2 pages of explanations about the objective maps. We can see that the editor has tried to add as many examples as possible to improve the comprehension of some of the cards.
