I'd like to change the work rate to all the same... if American spawns in turn 0, their work rate (2 turns for road) is double to China/India/Greece/Babylon/Egypt/Mali (4 turns for road). Unfair.
Maybe we can change like this:
All civs starts with work rate 1 (4 turns for road)
10% faster with bronze working (1.10)
10% faster with iron working (1.20)
10% faster with construction (1.30)
20% faster with engineering (1.50)
and finally 50% faster with steam power (2.00)
