Peace times over certain US holidays are nice, and help keep the game in context, but they need to be better thought out. The 3 biggest issues that come to mind are 1) things like WW completion times need to freeze (toll) during the peace time to hold the status quo, 2) various actions need to reviewed - the blackout window around city founding/takeover is much longer than the announced peacetime window, causing many revolts to expire because the CS is launched minutes late, 3) the peace time need to be announced well before they take effect, not a few days as they were this year.
