The impact of different game interfaces on people's game play has, so far, not received much attention in the scientific world. The present paper aims to contribute to a better understanding of the way people and their game play are affected by different game interfaces. A case study has therefore been undertaken to shed some more light on this issue. Two different input devices, a game pad and a modified exercise bike, were used for the game PAPERBOYTM, a game where players control a paperboy on a bike. Preliminary results indicate that people played the game in a similar way, independent of which input device they used. However, the bike seemed to have an influence on the participant's expectations about the kind of interactions it allowed.
