Actually, I was very confused by your post, which is why I wrote out so much. You said using percentages was useless and meaningless, and then you turned around and gave the exact reason why percentages were required (the vastly different population sizes).
Where in my posts did I "turn around and give the exact reason why percentages were required"? If you're referring to my:
"However, simply comparing percentages of death is useless and misleading. Europe had a much larger population than America did. In the end, the numbers of people that actually died are near equal using the most generous numbers by my approximation."
I did not mean to turn around. By pointing out that Europe had a larger population, I meant to
emphasize that while a larger percentage of Americans were killed, more Europeans died in total, which, to me, is what is used to measure "death toll". Anyway, I understand now that you meant to measure it differently all along anyway which is fine.
Just because the numbers now disagree with what the Spanish figured a few centuries ago doesn't mean you should dismiss all the modern research out of hand and say there isn't enough evidence.
I don't mean to "dismiss all the modern research". I simply stated the following: No one has provided evidence to establish the number (or percentage, for that matter) of Americans killed by disease. Therefore, it's impossible to compare with the black death of Europe.
Using archaeological evidence as well as limited sample sizes from known settlements where we can get good data, we can get a good picture of what destroyed the indigenous peoples.
Where is this evidenced, and if it is true, then what are the numbers of people that were killed?
Edit: On the other topic...
I also agree that a number of the European civilizations should be combined with America to create "The West". However, I understand why the game is the way that it is from a marketing perspective.
The problem arises because in the beginning of the game, a player is truly a "civilization". You're alone and quite different from everyone else. Once the world advances to around The Renaissance or so, everyone is really close together and quite similar. What were once civilizations are now more like nations. In general, the nations all get along if they're on the same unofficial team, religion, or general trade group. The concept of a "civilization" is now better defined as one of the previously mentioned groups of players/nations. Once the game advances to the Modern era, especially when the United Nations is built, it really feels like everyone is part of the same "civilization", except for maybe a few backward weirdos on a different continent.
The game mimics history rather well in this respect. The only real problem is that having America start out as its own civilization from the beginning of time doesn't make much sense (especially if the Native Americans are also in the game). The same is true of most of the European civilizations really. The reverse example of a modern day HRE or "Arabia" isn't quite as strikingly inappropriate. In conclusion, I would be happy to see some of the modern European civilizations combined with each other and perhaps also with America into a new civilization, and I realize that there is no chance that the game designers would ever actually do this.
