Why are Videopac games usually identified by number instead of title?
The most likely reason for this is that Videopac games were distributed in a number of European countries, each of which has a different national language. To cut costs, most games were printed with titles in a number of languages, so they could be distributed in multiple countries and still be understandable. Assigning Videopacs numbers provided a convenient, language-independent way to identify the games no matter what country they were in.
