Board Game Arena

The wiki says that adding options after release may break current games and I'm trying to understand why.
Is it just because the call to getGameStateValue may fail ? In this case couldn't I just encapsulate it in a "try" block and have a default behavior for old games in the "catch" ?
Or is there something trickier in the database or in the server state that might break ?

getGameStateValue wouldn't throw an exception, it would just return 0. Note that this value would not actually exist in the "global" table.

Introducing options can present a problem if your code is expecting a value from this function that isn't 0, or you've made other changes that would be incompatible.

Also, check with admins if there is an Arena season on it, some changes in setup may be needed.
