As the level cap has advanced, the developers have implemented a set of milestones in the leveling structure with associated level-specific quest lines that enable players access to powerful class-specific skills known as “talents” upon completion. As players journey through the world of Atlantica Online, their characters and mercenaries grow and develop, gaining access to new, more powerful skills and equipment along the way. In addition to the main quest line, the game features a variety of supplementary side quests rich with history and lore, a complex skill system, an in-depth crafting system, and a player housing system. Guilds and nations offer a variety of benefits to their members including passive boosts, guild-oriented dungeons, and ‘Guild Crafting’ where every member of a guild works together to complete a single craft. Up to ten guilds can unite under a single banner to form a Nation and go to war with other nations. The game design puts a strong emphasis on membership in guilds, which are permitted to own and customize towns like a business, profiting from the transactions that take place within their town.
