Both Inform 6 and Inform 7 have provisions for people to add support of
other languages, and a number of European languages have been added,
but there are none yet for Arabic. Because the game you make has to
understand Arabic sentences, just as games in English have to
understand English sentences, this is not easy. You must be an expert
in Inform, and you must be an expert in Arabic grammar, too.

would not all find the advice helpful.'"
