For those who don't know, Shogi is a game from Japan that is distinctly similar to Chess, but also different.
To save myself a ton of typing, here is a page with all of the rules. I believe that the difference is large enough to make having the game worth the effort.

To my knowledge, there is currently no accessible way of playing Shogi online, at least not in English. If I'm correct, this would mean the playroom has a unique thing that you can't find anywhere else.
