I set the national wonders where they are so that a player wouldn't be able to get them immediately after they became available. I wanted them to be available to expansionist players, but not without doing some work. You need 6 or 7 cities to qualify for the earlier wonders, and about 3 or 4 to qualify for the later wonders. With the changes to the cultural victory setting, I really don't see how you can win the game without having al least 6 or 7 cities.
If you're one of those players who likes to found 3 cities and "turtle up" for the rest of the game, then maybe this mod isn't for you, but I have been playing civ for 20 years now, going back to civ 1, and in my opinion you shouldn't be able to win the game that way.
Caution, rant ahead.
Imo, you should strive to be number 1 in all the demographic categories, and you shouldn't be able to win the game without being at least near the top in all of them. I consider the game won when I am dominant enough to be certain of winning both the science and domination victory paths, whichever one I wanted to choose. I play the game as a 4x-game, and I feel that everyone else should too, as far as their standard way of play. I mean, if you want to occasionally stay small and try to get a diplomatic victory or some such, that's fine- that option should be there. However, I don't think that it should be considered the "normal" way to play the game, and I certainly don't think that the game should be slanted to favor this style to the detriment of expansionistic styles, which is what I feel has happened over the last couple of years.
Do you guys remember when the game first came out, how luxuries gave 5 happiness and buildings either 4 or 5? This was how the original programmers and playtesters thought it should be, which was to favor the expansionist. Most every change since then has been to hamstring the expansionist and favor the turtle, to the point where I don't feel that expansionism is a viable strategy anymore without either modding or dropping down to such a level that the game isn't challenging.
To sum up, I feel that size should be the biggest factor in winning the game, and that trying to win without being the largest civ should be a real challenge, something that would normally require you to drop down a level or two to achieve.
