I always said that they needed a building in-between either the Amphitheater & the Museum, or between the Museum & the Broadcast Tower. Say a Concert Hall, or Opera Hall.....or something along those lines. I'd be happy enough for Amphitheaters to house either Great Music or Great Writing. Similarly, I've mentioned elsewhere that we need a great deal more theming bonuses in the game. In Civilization V, Great Wonders could generate theming bonuses-so that would be a great place to begin. However, why not theming bonuses for Amphitheaters, & possibly even theming bonuses from religious relics in religious buildings?
