100man-nin no Daikoukai Jidai

100man-nin no Daikoukai Jidai (100万人の大航海時代, Hyakuman-nin no Daikoukai Jidai; Literally: "One Million People's Age of Exploration") was a social game adaptation of the Uncharted Waters series.

Gameplay
The game's controls are restricted to simply tapping the touch screen or pressing icons to go from one menu to the next. Because the game is played in real time, players consume energy points for each action they take; AP is used for exploration tasks, BP is consumed when fighting enemies, and TP is spend during commerce-related activities like trading.

Quests serve as the main portion of the game, with each victory earning the players gold, ship materials, and fame. Weather changes also determine how fast a quest will progress. Like in the base titles, discovering new trade routes is still essential to raising money, though the gameplay can be made easier by purchasing items via micro-transactions.

Navigators are recruited by consuming gacha tickets. The stronger the navigator, the more effective they are at manning three of the player's ships.

It is recommended to befriend other players in order to earn more from trading and boss battles. PvP events include a competition to find hidden treasure.

To commemorate the game's opening service, early players received gacha tickets, discount prices for micro-transactions, and an invitation campaign that offered gold coins and rare navigators.

A second friend invitation campaign was held on February 29, 2012 with 1,000 gold coins as the prize for inviting one friend and a new navigator for inviting five.

From May 1 to May 15, 2012, a collaboration event with Uncharted Waters: Online allowed GAMECITY Citizen ID owners to acquire a serial code containing Liza and Alvero as bonus navigators.
