Don't ask what Super Mario can do for you. Ask what he can do for us. And what you can do for science.
We're running two separate data collection experiments using the Infinite Mario codebase. Both are connected with modelling player preferences and procedurally generating game levels.
If you have a few minutes to spare, please head over to this page and play a few short levels of Super Mario Bros and answer some simple questions. You will contribute to science and (hopefully) have fun at the same time.
