Atlantica Online is a dynamic turn-based MMORPG.
Atlantica is F2P (free to play), with an online shop called the Item Mall. Unlike many other freemium games, you can play Atlantica in its entirety for free. No part of the game (no content) is locked out from free players. There are items you can buy that can improve game play (see Licenses), but you can, and I have often done so for months at a time, play for zero dollars spent.
Currently Atlantica has 13 main character classes and over 70 mercenaries. There are 11 weapon types for melee, ranged and magic combat. Each character, main or mercenary, equips 1 or 2 weapons (or a shield) and various armors, such as chest, legs, gloves, boots, helmet, bracelets, earrings, necklace and more.
There are mounts, decorations, clothes and more. Unlike most other MMORPGs, you can use and resell almost all weapons, equipment, decorations, mounts, etc. after using them. There are some No-Trade (bind on pickup) items, but most are not.
Atlantica has player housing where you can have employees, craft, decorate and have feasts with your friends, guild and nation mates. Feasts give you temporary buffs and every player with a house and a Chef can hold one feast of each type daily.
Atlantica has multiple types of PvP.
Maximum level is currently 180.
The setting of Atlantica Online is Earth. You can complete quests on all continents and Atlantis, many of the dungeons are based on historical or legendary settings (e.g. Marksburg Castle, Shogun Castle of Death, Bran Castle, Grimm Woods, etc.), many of the NPCs are historical figures like Marco Polo, Columbus, Livingstone, etc. Even the mercenaries and monsters are based on history or legend (Grimm Brothers, Janissary) and make sense for their location.
The player community on Atlantica is one of the best I have ever encountered. Sure, there is the occasional jerk, but the vast majority of the community are friendly and helpful!
