Can't beat the AI? Is it too tame? Discuss the best strategies!
I don't know if its connected to the crazy agresssiveness of AI's but they almost never build roads on swamps / forests, and other terrains that don't increase trade, which means their cities are not connected. Cities which have forests between them are not connected at all, even on flat terrain they rarely build road connections. So after some time they fall behind too much, their cities are completely undeveloped. That's on Normal skill level. Aaand i play with at least 3 tiles between cities.
