I have created several new player guides for Atlantis, they were created for my own Atlantis game some time ago, yet I am sure that they are still useful. I have available a guide for new players, written by Fuzzyman, which can be found here.
I have created a sample help guide, designed to assist new players to Atlantis. It has the first few turns of a fictional faction and can be found here.
I also have a help page designed for new players who want to specialise in Magic factions. It is located here.
Finally, I am currently working on a guide for more experienced players. It details tactics of defence, attack, and common strategies. It also lists many dirty tricks employed by players over the past few years. Be sure to check back for that.

I have updated my Atlantis links page, so visit here to learn about more sites.
