Fencer: Since when we play a game we don't read every time the rules, and sometimes appear surprising rules-changes that we recognize in the middle of a match (last example: Hasami Shogi). So it would be nice if under the name of the game you put the date of the last rule change, and if this date is less than 4 weeks it should be given in red font,so that we are warned that a game has still the same name but not the same rules.
Or, as alternative, every time the rules are changed the name of the game should be changed also, in the example above "Hasami Shogi" in "Hasami Shogi Modern", and the old game can either continue with the old rules or if it is no longer interesting can be removed.
