Hey Sagwa
The majority of strats here are for mp. But if you can pick up some basic tips on rushing and expanding then most things will work out fine on sp.
The ai is fairly stupid really and once you have played a few times you will soon discover what it will land wont do. I have played way more sp than mp. I have won all victory types with each civ and completed every scenario.
As mentioned above once you learn how to win you will always win. It’s a great place to learn the game away from Zulu, American and Chinese rushers you will face online!! All of whom I hate!!

Makes mp very short!! So make sure you enjoy getting the tech wins, the world bank and the united nations because once you start mp you will most likely never do them again!!
Good luck.
