Natural Language (NL) mechanics are seemingly underutilized within modern game development and may be capable of inducing unexpected levels of agency within its users. This study focuses specifically on NL Input (NLI) and examines its capability of inducing an experience of agency, control, and freedom through an interactive fiction with a database searching context. To get a more nuanced result, a version of the artefact but with an NL Understanding (NLU) system will also be tested to create a baseline. Due to the limited time and resources, the NLU version will be employing the Wizard of Oz (WOZ) method. In total, five NLI tests and four NLU tests were performed and interview results indicated full experience of control and mixed experience of freedom and agency in both versions. Possible causes include the participants‘ genre preference and the limited content in the artefact.
