遂にワールドアドベンチャーが日本でも発売！！しかし肝心の公式がＣＭを打ってくれる気配が無いので、勝手に手描きＣＭをお送り します。この動画で、少しでも多くの人がソニックに興味を持って、あわよくば買ってくれるといいなあと思いながら作りました。　　【ソニワドを今初めて知った方へ】ｗｉｉ版が12 月18日発売。そしてＨＤ版（ＰＳ３・Ｘｂｏｘ360）が年が明けて、2月19日発売します。ニコニコにもトレーラーが上がって いるので、興味が湧いたら是非ご覧下さい！　　動画作成に際し、各種トレーラーに加え、30drawingさんのプレイ動画（sm5503340等）を勝手に参考にさせて戴き ました。厚く御礼申し上げます。　　あ、あと手前味噌ですがマイリスです。mylist/1795953

Translation:
At last, Sonic World Adventure now sells even in Japan!!
However, because there is no official announcement of a CM airing, I'm providing one at my own convenience.
With this animation, even to people with a little interest to Sonic, there is a chance to incite them to buy the game.

Wii Edition Sonic World Adventure on sale December 18th.
And HD Edition (Xbox 360 & PS3) will sell on February 19th this coming year.

Because the trailer at Niconico is gaining appreciation, interest is growing. Please take a took!
While working on the animation, in addition to various trailers, I took 20drawing-san's play video as reference (http://www.nicovideo.jp/watch/sm5503340).

I thank you all cordially.
A, and well here's my list (http://www.nicovideo.jp/mylist/1795953)

If you have a Niconico douga account, I highly recommend viewing this work at its original location: http://www.nicovideo.jp/watch/sm5573707
This animation has been created by 橙潤 (daidaijun) to make up for the lack of commercial for this game that has just been released in Japan. A big thank you to the author for providing a better quality of this animation (and to n3ko for helping me out~) and some much needed corrections.

Again, I am not the author of this work. This is merely a Sonic hand drawn animation channel. (less info)
