My suggestion for New Players is this:

1. Read the help menu thouroughly.
2. Choose an easy race to you get comfortable in the game. Undead is about the easiest race you can use just build archers, horsemen and elites and join an alliance so that you can have eyes to see who you can attack. You dont need mines except metal mines and smithies for your weapons. You dont need thieves or mages.

3. Disadvantage is your going to get robbed so you must accept this facet of the game.

I will discuss the other races later
