・まず最初に思い入れのある都道府県を選んでみましょう。例えば群馬県とか、もしくは群馬県とか、群馬県とかいいかもしれないですね。あと群馬県。 ・地域毎の特産品を収穫すると、J(JAPAN)が手に入ります。生える場所は、各地域(関東地方、近畿地方など)にざっくり振り分けられています。 ・特産品は一定時間で出現します。収穫してもまた一定時間経つと出現するので安心です。 ・特産品のLVを上げると、収穫時のJ(JAPAN)が増えます。 ・J(JAPAN)を使うことによって、各都道府県を制圧できます。 ・日本を全て制圧できると楽しいですね。 ・ついったーの登録をすると、制圧結果などをついーとできます。嫌われない程度に。 ・ひまつぶしでは、適当に作られたミニゲームが遊べます。ミニゲームでもJ(JAPAN)が少しだけ手に入ります。 ・一定数特産品を集めると、特産品図鑑に記録されます。これといっていいことはありませんが、気晴らしに。 *各都道府県の制圧に必要な数字、開始時の数字は人口を参考に設定されています。 *J(JAPAN)や、特産品レベル、制圧状況は各都道府県ごとにデータを持ちます。群馬県で稼いだ後栃木県でヒャッホーとかは出来ません。 *特産品の生えるまでの時間は共通です。 *特産品のチョイスに疑問を感じるかもしれませんが、ご了承ください。なんとなく選びました。 料理など(たこ焼きや牛タンなど)は避け、採れるという形が出来るものだけにしてあります。うどんは許してください。
