Well, I told you I make video games for a living, right? One game I worked on just came out last week "My Japanese Coach" on Nintendo DS, and this one's getting a lot of attention. I got my own copy and started playing it last night.
My role on this project was to draw the "Points of Interest" art, which I spent about half a day on each one of the twenty drawings. You start in Tokyo, so there's a drawing of Tokyo, then you move on from there through twenty sites of Japan over the course of 100 lessons.
Since all I did was spend two weeks making these drawings, I hadn't actually played the game before, and it's surpirsingly fun and effective. I think I played for an hour and a half or so without even realizing it and got through 4 lessons.
Anyways, I recommend this for anyone interested in learning a little bit of Japanese, or a lot if you really want to take the time with the game to study everything out carefully. It has 100 lessons and over 11,000 vocabulary words to learn. Not only that, it's pretty easy to sit and do. I always have trouble keeping papers organized when I'm studying things, but this is paper free. One of the best parts about learning Japanese on the ds is being able to draw the hiragana/kana (Japanese letters) right on the screen and trace them as they come up.
I also did the Point of Interest art for the "My Chinese Coach" game which came out a month ago. I imagine more people who read this blog would want to learn Japanese than Chinese, but it's out there if you are interested.
