You are speaking about peaceful deity CV?
So you are sayig that you can make 7 landmarks(one for each expo) and dig least 16 artifacts on standard size map? Otherwise you cant fill all museum slots on 8 cities. So thats at least 15 archaelogy dig outside of your borders. AIs dont get mad do you for digging so many?
Uffizi generates at least 36 tourism with NVC, aesthetics and cultural heritage sizes. How can you build 7 expos which all generates at least 36 tourism?
Bad math... very bad math...
36 tourism if you include cultural heritage, fine.
Say a landmark is 7 base culture (splitting the difference between an ancient one and a medieval one). Then, say, we went Freedom (the CV ideology of choice, although I'm more of an Order guy myself, Order's benefits are less easy to see, so we'll do what a typical tall tradition CV would do for a 1:1 comparison), and new deal is +4 culture. Then, say instead of cultural heritage, we do historical monuments for +4. That's 15 BASE culture per landmark. This is without using the two great artists Uffizi takes up. Those, go into the museum, which, with aesthetics is +8. Then, of course, we have a great work of writing, for +2. Hotel/Airport doubles the GW part, gives 15 for the landmark
This adds up to 35, for an expansion with ONE landmark.
There are always a couple of "free" artifacts in no mans land. You can have settlers built before (or immediately after) archeology triggers. AI always targets their own digs too, so you can be 20 turns later than the AI to archeology and still be able to found these cities.
For 8 cities (or hell, let's say 10), you'll need 21 great artists / artifacts to fill everything up. You get 1 free great artist. You'll generate at least 7 from the game before hitting internet. Faith buy 1, because 1k faith is nothing for a wide empire. That's 9. That's 12 artifacts you need to get. Assuming you have only 4 cities pre-archeology, because you screwed up, bad... then you'll have all the dig sites within 3 rounds of archeologists. 2 rounds if you have 6 cities like you damn well should. You can steal 1 from each civ without diplo consequences. As soon as you hit the tech (which you can Oxford if you need), you can send your soldiers (or workers, or missionaries) to squat on sites until your archeologists get there. It's not hard to pick up 12 artifacts. In a tradition game, you're encouraged to pick up 9. 3 more is not that much more.
Now, you're right, not EVERY city will have a landmark. In fact, you have zero control over your first X cities that you found, pre-archeology. But, ideology comes right after archeology, so you'll soon have a TON of happiness (happiness that scales per city no less), and in the meantime, a couple of city states and building zoos everywhere will do the trick and let you found the cities you need. If you have a 6-city start, go 10 cities (they don't have to be great cities). If you have a 4-city start, go 8 cities. In any case, you should easily end up with +4 cities working landmarks from what you would have had with a 4-city start.
Sorry, I underestimated and said 120+ before.
The real answer is: 35 x 4 = 140.
And, if you go 4-city then expand post-archeology, you can even still catch the AI for at least one of those wonders with a GE.
Try it sometime. Once you learn to manage happiness + expansion and "second/third wave" expansion while preserving science parity, you'll see that wide-CV is much easier than tall-CV. Remember, you're probably also picking a civ that has wide-friendly bonuses, and you're probably getting a religion with wide (there's something like a 65% chance now that a non-start bias start will have a faith pantheon available to you), to help out even more.
Now, the REAL question is whether this type of play benefits more from Tradition or Liberty start. This is actually debatable, because Tradition does give you more happiness and gold. But, liberty gives you fast workers (very important post-fertilizer, esp if you are building certain buildings), more culture, and +1 hammer.
edit: actually, do hotels multiply the theming bonus as part of the great works bonus? or is it just +1 tourism per GW? If the later, that's +31 instead of +35 per city... and so the final result is actually ~ +120, like my original claim. I knew I got that number from somewhere...
obviously these people saying liberty is better don't play CV deity that often (where success is based on size of capitol above all things); you can only have one NVC anyway so the extra few landmarks you get from your larger empire will hardly offset the wonders a tradition capitol can snag. It's actually the contrary: the higher the difficulty, the better tradition is. Liberty is better than tradition maybe up to prince or chieftain and that's about it 
sucks, or if there's a dearth of luxes I can expand to. (Not a good idea to go for the rapid expansion if you tank on 
, right?) But most of the time, neither of these are true. I see it as the difference between soccer and chess-- you have to make the same decision with the same accuracy, you just have to make one a lot quicker. Of course, I find soccer a lot more fun to watch.
