Systems and methods for using natural language processing (NLP) to control automated gameplay in one or more online games within an online gaming platform are disclosed. Exemplary implementations may: train a pretrained text-based system to generate sequences indicating one or more activities, wherein activities are associated with characteristics of user-controllable characters such that a particular user-controllable character having a particular characteristic may perform, within the online gaming platform, one or more activities from a particular set that is associated with the particular characteristic; receive user input describing one or more commands; generate, using the pretrained text-based system, a sequence indicating one or more activities based on the user input; transfer the generated sequence to the online gaming platform; effectuate automated execution of activities by the particular user-controllable character in accordance with the generated sequence.
