I need some opinions on my ideas of how to make an updated version of taikyoku shogi that happens to be realistic to play.

My current ideas on changes are.

Make the board grid smaller, likely 10x10.
Make the pieces be just 12 diferent types that repeat 16 times.
Pick randomly from a 12 number random throw or 12 dice, each piece.
Then repeat it 16 times.

Maybe make the initial layou be similar to shogi, and keep 8 + 8 rows of random pieces and then a middle row with the king at the center.

Make each piece be just a TGC card with the name of the card, a drawing of the waifu of each card, and then some indication of her movement.

Since there's only 12 diferent motions to remember, it should be a better design of the original.

Is there a core reason why we haven't seen yet AI vs AI matches of taikyouku shogi yet?
