Not worth its own thread I feel, so I'll put it here:
Grand Theft Auto V is the first CERO Z (18+) rated foreign title to reach 1 million copies sold in Japan. Munetatsu is an editor for Weekly Famitsu so this is most probably Famitsu's data.
『グランド・セフト・オートV』、国内累計100万本達成らしい! おめでとうございます!

Looks like we can add GTA VI to the list of games that will really move PS4s in Japan (when it comes in 2018 or whatever )
