The story was originally to have the player play the role of a nephew who had inherited a fortune from his aunt, to be spent only on the world's largest and most profitable theme park. The graphics were drawn and modelled using 3D Studio. Molyneux stated that each person takes about 200 bytes of memory, enough for them to have their own personality. The team travelled the world visiting theme parks and taking notes, and sound effects were sampled from real parks. Molyneux explained that they were going for as much realism as possible. There was to be a feature where a microphone is placed on a visitor and so the player could hear what they were saying, and multiplayer support was dropped two weeks prior to release because of a deadline. Multiplayer mode would have let players send thugs to other parks.
