My friends and I play a fair amount of Downforce. Great game, fun, strategic, with just enough luck. One of our house rules is that you are only allowed to bet once on each car. Playing on BGA, we have to remember which car we bet on and be sure to not bet on that car again. If we make a mistake, we collectively exclude that player from the winner's podium (by relentlessly mocking him, not via any technical means).
The reason we implemented this house rule is because our games got to be somewhat predictable. Whichever car was out in front usually got most, if not all, first-place bets. That in turn pushed it even farther into the lead. When it finished the race, just about every bet was for that car so whoever happened to own it won the game just about every single time. Once we implemented the house rule, suddenly it opened up the field. The end results were no longer predictable, you could win the constructor's title but still lose the game.
Is there any possibility of adding this as an optional rule?
