"All for One and One for All!" - the creedo of the Three Musketeers, and the European game industry, as well. Much to my astonishment, I recently learned that European game companies meet yearly TO HELP EACH OTHER!!
They review each other's new products at early stages to provide useful feedback. They do this to help their competitors make their products better. They do this in the interest of strengthening the entire game industry and therefore, indirectly, in the interest of each of the individual game companies, as well.
"Every man for himself" is the credo of American business, and anything that one might do that would benefit a competitor is abhorrent.
