Well no. Gandhi is quite a common name in India and it's always spelt "Gandhi" not "Ghandi"...
With Gandhi though there is only one accepted spelling
I am certain that these facts are true after the great G himself lived. But was it always the case?
Particularly, your claim about "only one accepted spelling" makes it seem that this strictness is due to the historical contributions of the great G. For example, if you can confirm that there are multiple ways of spelling other Indian names, then that fact adds credibility to this claim about the spelling of G's name being "the only way" due mostly to the great G's influence, and not necessarily due to the origination of the name itself.
only one accepted spelling which happens to be pretty logical given the way the name is pronounced.
Perhaps half of the forum members are pronouncing it incorrectly then, since it seems so logical to them that the misspelling looks correct, while it seems so logical to you that the opposite is true.
From my, admittedly limited, understanding of Indian languages, there exist both the "G" and "Gh" Gutteral Consonants. It could be that half of the forum members are using the pronunciation of the wrong Gutteral Consonant.
There is certainly a reasonable number of Indian Surnames which begin with either "Gha" or have "gha" as the start of the second syllable in them.
Perhaps you can give us what you use as the pronunciation of the great G's name, which, as you claim, would make it logically easier to remember the correct spelling.
The question is: What now? to expand my two options are through culture or war. I have almost all of the world wonders, and get a bunch of great people, so my culture is pretty booming.
If you choose to go for a Cultural game, then you will likely be quite fine with just your own continent. Try not to start wars, but be willing to join in on a war if it is against an AI that most AIs dislike. By "dislike" I mean where most AIs are Cautious, Annoyed, or Furious with said AI--when an AI has one of those attitudes to the AI that you declare war on, you will not get a negative Diplo hit with the AI that dislikes the war target.
Since you are technologically advanced, you can easily shut down all research. Try to get as close as possible to running 100% Culture, with the remainder of your Commerce Slider being set to produing Gold. So, say, you might have 70% Culture and 30% Gold, with 0% Science.
Also, since you likely already know Scientific Method and cannot build Monastaries, I suggest that you switch into the Organized Religion Civic, so that your Cities can build Missionaries. Build Missionaries in many of your Cities and spread them around. Then, build Temples in your Cities, so that you can build Cathedrals in your three Legendary-to-be Cities.
The Map Size will determine how many Temples you will need to build of each Religion before you are allowed to build Cathedrals. I believe that the numbers are roughly:
3 Temples all of the same Religion to unlock the Cathedral for that Religion for a Standard-sized map
4 such Temples for a Huge-sized map
2 such Temples for a Small-sized map
Your goal will be to build a lot of Cathedrals and other Culture-producing buildings, such as Theatres, in your 3 chosen Legendary-to-be Cities.
If you have two Cities with a lot of Food, then you can strongly consider switching into Caste System when you switch into Organized Religion. Then, be sure to hire a lot of Artist Specialists in your Food-heavy Cities. You will be trying to generate Great Arists, who can be either settled or can "Create a Great Works" in one of your three Legendary-to-be Cities.
Other Cities, which are not your 3 chosen Legendary-to-be when they are done with building Missionaries and Temples, can build Wealth.
As far as choosing the 3 Legendary-to-be Cities, that's up to you, but some general guidelines are:
a) Cities with a lot of World Wonders can work well
b) Cities with a lot of matured Cottages can work well
If you have a lot of such Cities, then you can differentiate the better ones as being those that also have some surplus Food from Food-based Resources AND have some reasonable production (12 base Hammers or more).
As far as Diplomacy goes, figure out who is whose Worst Enemy. Generally, if AI #1 treats at least one other AI with an Annoyed or Furious Attitude (check the F4 screen and look at the GLANCE tab), then AI #1 will have a Worst Enemy.
Decide which AIs are the most disliked in the world (if you have 6 AI opponents, then you'll probably pick two AIs). Treat those AIs as YOUR enemies and try not to give into their requests.
For all of the other AIs, do your best to give into their requests. If they ask you to switch Civics or Religions, you can strongly consider the idea, as you can switch back again 5 turns later without an Anarchy cost, as you are a Spiritual Leader. If they ask for a tech, give it to them. If they ask for a small sum of Gold, give it to them. If they ask you to stop trading with one of the AIs that you have decided is one of YOUR enemies, then you should strongly consider agreeing to do so. Basically, be as nice as you possibly can to the AIs that you are not treating as YOUR enemies.
This way, you will have AI help if you get dragged into a war, while you will only have a few enemies, so the whole world won't be against you in a war.
