dragons for napoléon, keep musketeers for Louis XIV
for the tech depending on resources, ok but be careful: maybe you discover horses with horseback riding, so needing horses for horseback riding will be dangerous
well, my two cents
They took away the dinasaur on the world map - so i do not think they will add dragons.

(only joking - I know its a typo.)
On resources: in DYP and R&R they became visible a few techs before they could be used. This gave you time to either road, colonise or build a city near them before they were needed.
Two more ideas for modding.
1. Unit Support.
Assuming units need support as in Civ3, what happens whwn the money runs out?
Are they disbanded as in Civ3?
If the answer is yes I would like to see the following in a mod.
When you can not afford the upkeep of a unit (for what ever reason) the unit is made immobile, instead of it being disbanded.
You can no longer give it orders - it has mutinied or run out of supplies.
You only regain control of that unit when you have the gold to pay its wages/supplies.
To simulate its lack of readiness for combat the following should also happen.
Each turn it is imobile it should loose 5% of its defense capability. The reverse of a defending unit.
Also if it is attacked and it has first strike capability that should not apply.
Maybe it should also lose a few damage points - to represent those soldiers who mutiny and leave the main body.
2. Great Leaders.
I think there should be a military great leader also.
They could be used for:
1. Has the potential to trigger a Golden Age (or GA). Requires two Great People for the first GA
2. They can discover a Military-Related Technology, for example, Military Tradition.
3. Increases the defence and attack abilities of units they are stacked with by 25%.
4. Build military improvements - e.g. the castle.
They could be generated :
1. Randomly through battles.
2. Points from military specialists. (Which would also need to be added).
3. Points could be accumulated from military improvements.
The military specialist would also improve the experiance levels of units built in that city. Like barracks.
