Didn't do too much coding today either. However, I did some thinking (again) about what leaders will the player be able to choose.
Here is what I came up with:

• Gandhi - diplomacy bonus
• Hannibal Barca - attack bonus
• Julius Caesar - defense bonus
• Abraham Lincoln - small food, wood and stone bonus
• Benjamin Franklin - research bonus

If you think that any of the leaders should be changed, feel free to suggest any others. :)
The exact amount of bonuses will be determined when I will do balancing.
