KotDB: I would agree with you that games with the same board, but having different rules needs something like a different color border to make the game 'stand out' and tell you not to play the game like regular chess. Of course I've stopped playing Extinction Chess since when I start playing games, my eyes go strait to the board and don't spend the extra time looking closly at the name of the game - so I end up playing it like regular chess which of course is bad.

Since there is a small amount of players who do not like this game to have a different color, then what Walter Montego said would be a great suggestion.

Make a "chess board color" tab in the settings.

Have 3 options - (1) All boards with same white border, (2) default BK with each board different - having a different color picked for each game (default choice - like current, except all games having different color boarder), or (3) Pick colors for each game below

Then list each game with a drop down box that list 25 colors in which the person can go through each game and click the color they want for each.

Anyway, bottom line in my opinion - if the boards look the same, and the rules are different - there needs to be a different border color for each. To lose a game because you did not know what game you are playing is just stupid - it is a stupid way to lose, and a stupid way to win against someone else. To lose because you got beat in the game you are playing - then that is OK.
