Atlantica Online

The game features a persistent world populated by player-generated characters and NPCs. At character creation, a player selects one of seven basic classes and can then customize the character's appearance. There are no races to choose from; only humans are available. The character's class decides what armor that character can wear and what weapons and skills that character can use in battle.

Players do not fight with the starting character alone; as each character levels up, it can acquire player-controlled mercenaries. During the mandatory tutorial section at the beginning of the game, a player chooses his/her first two mercenaries; as the character gains levels, it can control more mercenaries, up to the maximum of eight, which makes for a party of maximum size nine. Players can store additional mercenaries in mercenary rooms.

All characters can, in addition to their battle skills, pursue a number of different crafting abilities.

The game design puts strong emphasis on the concept of guilds. Guilds can control the various towns on the game map. Strong guilds can found nations and wage war on one another.

Battle in Atlantica Online is rather unusual for the genre as it is turn-based. Representations of hostile parties wander around the landscape; if a player touches such a representation, his/her party and the enemy party are transferred to a separate battlefield similar in fashion to battles in the Final Fantasy series and remain there until the battle is resolved.
