Microsoft Gaming chief Phil Spencer has confirmed that the company will be porting more Xbox first-party titles to other platforms in the future. Xbox first announced its seismic deviation from console exclusivity earlier this year, when it revealed that four first-party titles from its back catalog would head to rival platforms, PlayStation and Nintendo. At the time, Spencer clarified that this initial batch of multiplatform titles wasn't a sign that the "floodgates" were opening, but it appears Microsoft isn't done porting.
