So, seeing the (seemingly) positive reception that I've had from making the previous suggestions list, I think I might be inclined to making another list. All the games here would be part of an existing family, and I'll be making a case for all of them. Most games here are listed on either iggamecenter, Ai Ai, or boardspace.net

1. TriGo (Steve Metzger), Rosette (Mark Berger), and Sygo (Christian Freeling)

Some more Go-like games that are actually closer to the game of Go than Blooms (which is closer to a "variant" named Atari Go, which to be fair could be included in it's own right). In these games, the differences are :

- In TriGo, each player plays twice in a turn (similar to in Blooms) in the vertices of a triangular board (which means it's a hexagonal board!)
- In Sygo, stones FLIP colors when captured (similar to in Othello) instead of being removed. This pretty much eliminates the Ko rule.
- In Rosette, stones are played in the vertices of a hexagonal board (which means it's a triangular board!). To solve the issues of minimum amounts of liberties, the hexagonal cells themselves (which can't be played on) BECOME eyes when all of it's vertices are filled with stones of the same color.

and finally for reference, Atari Go is almost identical to Go, except the goal is to capture a set amount of stones (instead of controlling bigger amounts of territory).

2. Yari Shogi (Christian Freeling) and Cannon Shogi (Peter Michaelsen)

Both of these games are very fresh takes on Shogi. Yari Shogi is quite a violent game in that all the pieces (except pawns) have the ability to move forwards like a Rook. Meanwhile, Cannon Shogi has lots of cannons that brings quite a Xiangqi feel to the game.

3. Shakala (Christian Freeling)

I've personally never played this myself, however I did read the rules, and the mechanics in this game sounds like it'd make for a really neat game. Considering it's made by the guy behind Dameo himself, I have confidence that it's the case.

4. Alveole (Motion Twin)

Apparently, this one originated as a board game made by the same people behind the video game Dead Cells, so this might have some licensing issues (I think?). Aside from that, it's a really faithful implementation of Lines of Action into a hexagonal board, so it'd be nice to have it here. This and Tournoy are the only games that are not featured in any of these three sites (Tournoy being in Cazaux's personal site and Alveole being playable in Board Game Arena).

5. Tournoy (Jean-Louis Cazaux) and Rotary (Christian Freeling)

Two very weird, yet highly creative variants of Chess that I think deserves more spotlight (and more platforms for them both to be played in). Both variants utilize pieces that rotate as their main gimmick, with Tournoy also using rotating pieces for the pawns (whereas Rotary uses regular pawns). Both games can trace their origins to a 3M game called "Ploy".

6. Emergo (Christian Freeling and Ed Van Zon) and Bushka (Christian Freeling)

Also very quirky interpretations of an existing family of games, this time the Draughts family. Both have very fun mechanics (Bushka having a "contact capture" mechanic that's highly uncommon in board games, with the only other game featuring it that I can think of being the game of Fanorona, with a similar capturing mechanic seen in Ultima, a chess variant, while Emergo has the board empty at the start of the game, with players initially placing all their pieces) that will definitely bring something unique to the table in terms of Draughts type of games.

Hopefully this list is coherent enough, sorry for the amateurish writing.

Fun fact : Rosette was actually being offered by the author to a Japanese company to be marketed as "The War of the Roses" somewhere in the 70s!

Hi @TobiasOfTheEast thanks for the write up, always interesting to read about other games and variants, some of which I was aware of and some I was not!

Any prospective Chess, Shogi and Xiangqi variants ideally need to be added into the FairyStockfish engine for us to be able to easily add them and quickly bring them into our ecosystem with the maximum number of extended features.

I think its unlikely we add any more Draughts variants without taking care of our existing Draughts variants first.

I've made a note of these games/variants for future consideration. The most interesting to me is Alveole, although I agree the licensing could be an issue unfortunately.
