Would anyone like to play Modern Chess? It's Chess on a 9x9 board with an extra Prime Minister (or Minister/Archbishop = B + N) and a 9th pawn. It looks like fun.
While in the original setup both Bishops start up in the dark squares, there is a "Bishop-Castling" rule in this game which allows a player to swap places for one (and only one) of the Bishops with the adjacent Knight, Queen or Minister, therefore ending up with a Bishop on the light squares, just like in normal chess. The Bishop castling is optional though, and if one feels that playing with both Bishops on the dark squares is better, they can do so.
