It seems to me Minishogi could be played pretty easily with a standard piecepack. What do you think?

I agree. For piecepacks with non-standard suits I'd suggest the same pieces as I did in Shogi but if you have a standard piecepack I'd probably use instead sun coin backs for gold generals and moon coin backs for silver generals (easy mnemonic because in alchemy gold was represented by a sun symbol and silver by a moon symbol).

In the past month I've been pretty busy with piecepackr development/documentation but still have more non-reverse-compatible API, print-and-play layout changes, and documentation to do before it makes sense to share with the group.

I'm subscribed to your GitHub? repo, so I see exactly how hard you've been working -- which is pretty damn hard. :)

I had a similar thought about Gold and Silver, but in Minishogi, the Silver promotes to a Gold, and there is no piecepack coin with a Moon on one side and a Sun on the other.

I'm working on it. I'm regretfully coming to the conclusion that unless I want to swap out coins when one gets promoted, I need two standard piecepacks for even this smol variant...

I'd forgotten that your rules show promotion by 90-degree rotation. Worth thinking about.

You could stack the moon on top of the sun and flip them together..

Besides promotion by 90-degree rotation as I suggested for Shogi for Minishogi you'll also have enough extra coins that you could also do checkers-kings-style promotions (i.e. upon promotion slide an extra coin underneath and when a promoted piece is captured first take the extra coin away). This would be harder to make 2D piecepackr diagrams for than 90-degree rotation promotions but should work well in 3D real life (I guess if you had to you could draw slightly staggered coins).

Dan, although you could stack the moon on top of the sun and flip them together for Silver generals it would be hard to do similar promotion schemes for Pawn (which also promotes to Gold General), Bishop, and Rook especially since you want to be able to tell apart a promoted Pawn, a promoted Silver General, and an unpromoted Gold General (these have different values to the opponent as pieces to be captured). There is enough extra piecepack components that I think you could make such a scheme work but I think using a 90-degree-rotation or checker-kings-style promotion scheme is probably simpler to implement and remember what all the pieces are.

Inspired by the oblique projection in the Fuji-San academic paper I've added some basic oblique projection support to piecepackr which should (for most but not all games) allow one to tell if there are stacked coins/tiles. However right now requires the programmer to hustle a bit more than they would need to in order to make diagrams with the default "top view" orthographic projection.

RonHaleEvans what should be the wiki best practices for records of piecepack game instances (completed or in progress)? Should they go in an examples section in the relevant game page? What about the several piecepack games you said you wanted to play in January on your blog (that we agreed would be good to generate diagrams and animations for) that I started a page to collect?
