So, here's what I've come up with. As always, this is just preliminary ideas and by no means set in stone, or even any good. =]
Bangladesh (Sheikh Hasina)
Start Bias: Coastal
UA:
Land Of Rivers
The
Gold bonus from International Trade Routes sent to or from Bangladeshi Cities on Rivers is doubled and applies to Sea Trade Routes as well. Farms and Pastures on River Tiles generate +1
Food and
Faith.
UU:
Blue Helmet (replaces Marine)
Standard Marine bonuses. Additionally, starts with Medic I and the unique promotion "Cream Of The Peacekeepers", which allows it to generate 10 Influence with the nearest Friendly or Allied City-State per kill. Upgrades to X-COM Squad.
UB:
Hat (replaces Market)
+1 and +25%
Gold. +1
Gold from incoming and outgoing Trade Routes. +1
Gold and
Faith per City-State connected to your Trade Network by a Road.

So, this is a Bengali-influenced trading Civ with an emphasis on doing something nobody in their right mind generally does: building roads to City-States. In fact, City-State influence is the core mechanic of this Civ, referencing modern Bangladesh's status as the founder of a lot of international co-prosperity organizations in South Asia. This is also reflected in the UU's name and traits; "The Blue Helmets" is another name for the UN's Peacekeeper Force, and Bangladesh is the largest supplier of military manpower to that august body. Weird, that.
The Hat is an ancient kind of Bangladeshi marketplace, which made it an ideal fit for their Gold-focused nature, and I liked the idea of it being used to form good relationships with other, lesser Civilizations ingame. It also works from a balance perspective; a few Hats here and there make it much more profitable to build roads to City-States, as you can easily sink the cost of the roads. Plus I've recently been exposed to TF2. =]
Finally, the UA name is just the nickname for Bangladesh. I'd actually forgotten about this when I started this idea, but Land Trade Routes get a Gold bonus for being on a river. Increasing this bonus and making apply to Sea Trade Routes just made a lot of sense to me. The bit with River tiles contributing faith and extra food is just a reference to the mighty Brahmaputra river system, whose delta forms basically all of Bangladesh.
Hope that's of use! =]
