Okay, time for commentage.
How do people feel about having the game start at an equivalent to about 1200 BC?
Depends on what do you mean under that... An advanced start? A post-Dark Age start? Or simply Iron Age start?
Still, I personally think that given your system it would be best to start in a 2000 BC equivalent, both technologically and historically.
Since every nation has its roots in some place that was essentially chosen for particular qualities and not because it was somewhere in particular in the world, perhaps we should begin this game like that. Players would post a description of the earliest taking shape of their nation and the kind of place where that happened. Things like a broad river valley with nearby mountains or on a large island with rich fishing grounds or in trackless plains of tall grass and herds of game.
Then, based on those, I do a BT to move them forward to the game start. When that is finished they go on the map in a place that matches their start and BT? Like RL, players would discover where they are in the world only after they put down roots and begin to build their nation.
The idea is largely approved, though I again question the need for a BT within your system; the other problems here have already been covered.
The game effect I think I want is higher taxes should mean more money to spend, but an unhappier population. Economic growth would be "funded" by spending on things that drive growth, but the player decides whether or not to capture that gtrowth through taxes or not. The domestic economy could be taxed differently than trade.
This raises the question of how important (in the game) should a "happy" population be and should fear of rebellion be a significant factor in game play? I pretty much ignored this in BirdNES.
Note that people generally get used to high taxes (well, within reasonable limits ofcourse); it's actually the raising of the taxes that causes the most dissent. Remember - humans are extremelly complacent; all historical rebellions were ultimately caused by outside change.
I do believe that various complicated social processes - including rebellions - should be covered in more detail; sadly, I am not sure as to how exactly it should be done. Still, perhaps some sort of stability stat would help? Wars, natural disasters, reforms (in this case meaning drastic changes of policy), conflicted social change and so forth will naturally decrease social stability, making rebellions and radicalism in general all the more likely (but also untying the government's hands, I suppose; same reforms are far easier to pull off when you don't have much to lose in the terms of stability).
In practice though, the moderator would almost certainly have to enforce it actively ("No, sorry, rewrite it"), which is the same net effect as making a stipulation as to what range appears in the cradle.
Not exactly - this way it would be a theme developed over time and under greater influence of the players. That makes an appreciable difference.
If in creating their nations, players gave them a vague label and said that their nation was similar in its roots to X (East Asian, Mediterranean, Sub Saharan Africa, Northern European, Ancient Middle Eastern, Steppe, North American, Mesoamerican, South American, South Asian, other). Nations that do not fit would called "other" and either grouped together or spread amonst the named groups. I would place the nations in appropriate cradles.
I kind of disagree; originality would be prefferable inasmuch as it fits in. Also, remember that one of the best points of the Fresh Start is that civilisations develop over time. Furthermore, they influence each other's development. So I don't think there is any point to putting similar civilisations close together; rather, they should be groupped by geographical convenience/appropriateness on a premade but unrevealed map.
That's one idea, anyway
(most notably, the Romans),
And then on later stages, I would recall.
Of course, players could also ignore this for reasons like the scramble for Africa; manpower and prestige
With according long-term consequences for Third Republic-style colonialism (I believe Disenfrancised did a rant on that one a while back).
