If you have never heard of doujin game, you can read the brief explanation on Wikipedia. As for doujin fighting game, there are quite a few out there, but I would call these the "Big 3":
1. Melty Blood series
2. Eternal Fighter Zero
3. Touhou series
The 3 of them are all well-written fighting games with distinct systems. Our channel is about the 3rd one, mostly about the latest one of the series, Touhou Hisouten Soku. You can find all its information, including link to a very comprehensive wiki, and embedded webchat client here.
