Tales of Phantasia
Both "Tales of Phantasia" and "Star Ocean" stretched the power of the Super Famicom to its limits, with a total of 48 megabits of data. Additionally, "Star Ocean" was also one of two games that used a special S-DD1 chip to aid in compression of almost all graphics and map data, meaning that it effectively stored even more data than "Tales of Phantasia", though the compression led to a lower audio quality. The game also featured special technology called a "Flexible Voice Driver" that allowed for the compression of sound, allowing for voice clips for characters when in battles, another trait that was both very rare for a Super Famicom game, and shared with "Tales of Phantasia". Different voice clips would be played depending on the scenario; if the characters were confronted by weak enemies, they may say something more confident, where as if confronted by strong enemies, they may say something more fearful or frantic. Mode 7 graphics were generated using software, and appear when items pop out of treasure chests; the need for extra tiles, however, limited the graphical effects implementation. The game also featured surround sound. Planning for a sequel began as soon as development was completed on "Star Ocean". Feedback about weak boss monsters later led to more challenging battles in "".
