EDIT #1: I forgot the Circus Maximus. It is now in the list as a reminder. This subject's been in my head for a couple games now, thanks to the Wonder Elimination thread and just my own play experience. Of all the National Wonders, how many do you build over the course of the game? For Reference, here's a list of them: National College (Libraries in all Cities) National Epic (Monument in all cities) Heroic Epic (Barracks in all cities) Grand Temple (Temple in all cities, found religion) East India Company (Market in all cities) Ironworks (Workshop in all cities) Hermitage (Opera House in all cities) National Visitor's Center (Hotel in all cities) National Intelligence Agency (Police Station in all cities) Oxford University (University in all cities) Circus Maximus (Colosseum in all cities) For my own play, I'd say I usually build 4-6 of them, but some of them I really struggle with. The National College is too good not to use, and I always build a National Epic as it's so easy early game with Legalism. If I have a religion, I usually get the Grand Temple sooner or later. Oxford University I build later in the game. The rest vary somewhere between 'build occasionally', and 'almost never'. I often try for a Hermitage, and end up getting it sometime late. The Ironworks is nice, and I'll try to get it in my Military / Production city, but I find that I am often busy or not eligible to build it when I have a free moment. EDIT #1: I forgot the Circus Maximus, but when I do remember it exists, I build it. Generally it depends on my happiness levels, whether all the gold and hammers for the Colosseum are worth it. The 'almost never' ones are the rest. I never bother putting police stations in every city unless I'm playing very, very tall. The Heroic Epic seems really nice on paper, but I never find the production or money to put a Barracks in every city, and even if I did my military is usually built and I won't gain much from this Wonder. Visitor's center is only if I'm playing tall and touristy, but frankly I'd rather go wider and have more museums for Artifacts. I could see building it as France playing tall, but otherwise I'm not putting Hotels in cities with basically no great works or Culture improvements. What are everyone else's experiences with the National Wonders? Am I missing some really good Wonders or am I overbuilding them?
