|In essence, the game is quite the same as its Super NES predecessor, International Superstar Soccer Deluxe, vastly upgraded for the Nintendo 64, with 3D animation, fluid and fast-paced gameplay. While it kept largely the same team roster (with the teams now sporting near-authentic kits), South Africa debuted in this game as a selectable side, replacing Morocco. However, the Japanese version of ISS 64 has teams that are not present in the overseas versions, such as Bolivia, Yugoslavia, Canada and Saudi Arabia.|
There are six game modes, including a fun multiplayer 1-4 player (except for everyone's icons being the same color) exhibition mode and training. International Cup has the player competing against a range of teams from around the world in a round robin tournament; World League is a series of 70 matches against every one of other teams in the game.
The player can also contest a penalty shoot-out competition with up to 4 players, or attempt to complete certain scenario games (where each game is set up with a specific goal, for example scoring a goal within a given time limit, or stopping the opposing team from scoring, etc.).
