Perhaps noticing a few of his soldiers dropping like flies, Microsoft's Larry "Major Nelson" Hryb spoke with Freeverse regarding the fits of motion sickness caused by their latest release, Marathon: Durandal.
While they're not offering a technical solution just yet, they do plan on giving folks fair warning and a bit of advice. Within the next few days, Freeverse will "implement a [dashboard] message on the download screen to advise users on steps they can take if this affects them and are investigating other options to address the issue."
When we spoke to Marathon:Durandal's project lead, Bruce Morrison, he suggested a simple flip of the "camera bob" option and that seemed to work wonders. With so many folks -- many with no prior history of motion sickness -- getting ill from playing, it may still require an alteration of the game itself.
