I have no problem with being less Euro/West-centric as long as wonders are chosen for valid reasons and not merely for the sake of getting away from the Eurocentrism.
While I think the Hoover Dam stands out, the Three Gorges Damn certainly is noteable. However, for all we know (and let us hope this won't be the case) it could fail and collapse after a handfull of years and result in a lot of people dying. Again, I hope that is not the case. I'm just pointing out that not only does the Hoover Dam stand out, it's also survived for quite some time and proven itself reliable for the most part. Engineering disastors do happen, sadly. Seeing as they brought back the Statue of Liberty, I'm not so bothered by it as I otherwise would be. I'm almost for saying that each Civ should have a wonder that could be associated with it (nothing comes to mind for the Mongols, Aztecs, or Germans off the top of my head). I think adding Chichen Itza, for example, was a good move IMHO. The Mayan built roughly ten times as many pyramids as the Egyptians (one for every city practicly), although size may be different (certainly most would be smaller then the Great Pyramid).
Newton's University, Adam Smith's Trading Company, Marco Polo's Voyage, and many other western based 'wonders' deserve representation either for thier signifigance as a building/event/organization/marker of a turning point. Now the west (at least in recent centuries) has certainly been the center of power (not to put down China (especially) or the Arabs as they too have been centers of power both in the past and even today) and that could put a spin on such things. Fair? No, it isn't.
Personally I think China qualifies as deserving several wonders, it is an ancient culture with a magnificant history, but they certainly have more then one already. The Great Wall, in addition to the Pyramids, is in the top two of most deserving of being recognized as a Wonder. The Great Wall will likely always be in Civ, as it should be. The Forbidden Palace is also in it, albeit a small wonder. America has two: The Manhatten Project, and either the Statue of Liberty or the Hoover Dam. While the SoL is a gift from France (and therefore could qualify as a French wonder if you wanted to be technical), I'd still rather have the SoL representing the USA instead of the Hoover Dam. The USA could also claim the UN to a degree (it being in New York City... the HQ building being built by Americans... America being one of the main proponents for it)... but to be fair, Geneva, Switzerland also houses UN facilities.
America and China both do have small wonders (Mt. Rushmore, Forbidden Palace) and America does get some more Wonders (Hollywood, Broadway, The Pentagon (full wonder now), the Statue of Liberty, possibly the Internet (altough the WWW is International/Swiss) so as a patriotic American I'm certainly in no posistion to complain about my beloved country being under-represented. I'd personaly rather have the Hoover Dam the Hollywood or Broadway, but to give that honor to China while having one of those... meh, fair trade especially seeing the effect Hollywood or Broadway might have.
It's to bad that there isn't something between Wonder and Small wonder, perhaps a level where only one or two could be built... one would be the Hoover Dam (first built historicaly, and thus the first one for the first Civ to build) the other Three Gorges. The other possibility would be to have both... either seperate from each other, or connected. IE: Scenario #1: Hoover Dam is worth X hammers and has X strength effect, Three Gorges costs 3X hammers and has 3X effect.... OR only one "Large Dam" project could be built... you choose which one... so Three Gorges would be riskier in a race to build "Large Dam" but the payoff greater.
I'll probably grumble a little about it, but seeing as they're bringing back the Statue of Liberty (which is more known... and more known as American globally) I'll accept it. I reserve the right, for whatever reasons (IE, it suffers a catastrophe during/after construction, it's abandoned, personal taste, someone stole my soda... whatever) to change the name or even change it back. I might make it the Hoover Dam for certain scenarios I have in mind, but still... it's basically the same thing. As long as we're not renaming it for the sole sake of being less Eurocentric, and are renaming it due to it deserving to be reckognized over "Old western wonder X" then I have no problem. I am glad to see new/different wonders (Chichen Itza makes me very happy), but I want them to be ones that certainly deserve the honor (Taj Mahal and Angor Wat are others I'm very happy they added)
Again, as long as each wonder in the game stands of its own merit being in the game (and wasn't thrown in just to represent everyone), then that's fine by me. Now a lot of Western 'wonders' (I use quotes as they're not always buildings, but could be events/undertakings/organizations/etc) certainly stand up for being counted... and they've pretty much been in Civ games to date. They shouldn't be thrown away for fearing of being overly Westernized alone.
