Ultimate Mortal Kombat 3 (UMK3) is a fighting game in the Mortal Kombat series, originally developed and released by Midway Games to arcades in 1995. It is an update of 1995's earlier Mortal Kombat 3 (MK3) with an altered gameplay system, additional characters and stages, and some new features. Several home port versions of the game were soon released after the arcade original, although none were completely identical to the arcade version. Later home versions emulated the arcade original with more accuracy, including Mortal Kombat Arcade Kollection, which included the game alongside its predecessors Mortal Kombat and Mortal Kombat II. Some versions were released under different titles: Mortal Kombat Advance for the Game Boy Advance and Ultimate Mortal Kombat for the Nintendo DS. The iPhone/iPod version recreates the game using a 3D graphics engine. UMK3 was well received and has been considered a high point for the Mortal Kombat series. It was later updated to include more content from previous games in the series as part of the console-exclusive Mortal Kombat Trilogy.

Uncharted Waters, normally released as Daikoukai Jidai (大航海時代?), is a popular Japanese video game series produced by Koei under its "Rekoeition" brand. It is a simulation and role-playing video game series dealing with sailing and trading, themed around the Age of Discovery. In the games, the player takes up the role of a captain (or commodore in some translations) and manages a seagoing fleet to participate in trades, privateering, treasure hunting, exploration, and plain piracy. Even though the series is largely open-ended, there is still a loose plot which requires the player to follow certain paths, and deviating from these paths may stall the progress of the story. In East Asia, the series has a large cult following, but it has not received much recognition outside the region. However, it has been compared to the earlier Sid Meier's Pirates! in gameplay and theme.
