If you want to have any credibility, when asking for a change, then start a change yourself, and for example do not fall into american wrong standards like abbreviating everything. IE at best can mean Internet Explorer, certainly not Indoeuropean. The essence of communication is to transfer/exchange your thoughts with other people, the essence of american communication is to produce noise or waste bytes or paper by communicating nothing. A typical american sentence is GTFO STFU, the biggest cities in America are NYC and LA, and the country is called USA.
All this just to say that if you write Indoeuropean as IE, you are not entitled to ask for the inclusion of a Dravidian civilization. You follow the american steretypes yet pretend they themselves not do it ? Firaxis is american and will only include stereotypes in their game beacuse their game is a tool to allow americans to play with civilizations, not a tool to let them learn more about them (are we kidding ?). For example the americans must not know that Dravidians aren't the same as Indians, that Italians aren't Romans, that the Italian language isn't the closest grammatically to Latin, that Latin isn't the official language of Vatican and all that, they would be overwhelmed by too many new informations. So when they think of the Indian peninsula, they can only think of one civilization, that being India. Why ? Because that's easy. If it's the Indian pensinsula, it must be the Indian civilization, that's obvious. When they think of the Italian peninsula, they think of one civilization, that being the Roman one. Why ? By the previous logic Italian would be easier. But Americans have contorted logics. Because the American civilization is the modern version of the Roman one (probably more so than the Italian civilization), they have things in common, and they have nothing in common with Italians, so these are scrapped and considered a lowly civilization that never won a war, while the Romans... boy, they won and conquered so much, killed, deported, enslaved, vassalized, stole so much from other civilizations, that they are INDEED worth a lot more. Oh, and by the way, the Romans were good. When they declared war to the Gauls and steamrolled them, it was to defend Massilia (Marseilles). Reminds me of when the USA stepped in to defend Kuwait. But I digress...: Dravidians and Italians aren't good for an american game. Period.
