Historically, baseball has been described as America’s national past time. However, there might be another activity better suited to this title … and that is playing video games.

Joining me today to dive into the world of O.R. and video games is Xiao Lei, assistant professor with the University of Hong Kong, a self-confessed lover of video games who is also lucky enough to get to help advance the role O.R. in gaming.
