Star Wars Episode I: The Gungan Frontier is a video game by Lucas Learning. The players must introduce organisms to the Naboo moon of Ohma-D'un in an attempt to develop a stable ecosystem capable of supporting Gungan colonization.
After the opening crawl ends, it cuts to a sequence of Obi-Wan Kenobi and Queen Amidala's ship landing in Otoh Gunga. From there, it cuts to the Gungan council room where Boss Nass is waiting. He tells them about the problem at hand, and asks which one of them will help to build the new ecosystem. At this point, the player chooses which character to play as. This makes no difference to the outcome of the game, or any ensuing plot details.
Once the player has chosen, Boss Nass provides you with the aid of the Kresch, Jar Jar Binks, and R2-D2. You commence to loading your ship and taking off toward the moon. Once you choose a good spot from which to begin building your ecosystem, you land the ship on the moon, and the sensors are placed. From here, gameplay begins. You release the plants and animals from your ship as you please, and allow them to grow and multiply. The Gungans will occasionally harvest a plant or animal, and use it to help build a bubble city. You can change the amount of life forms that the Gungans take, as well as check on the progress of the Bubble City on the control panel. The game never ends from there, you just have to maintain your ecosystem, as well as the bubble city and Gungan population, as long as you can.
