If the Xbox One was backwards compatible I would have bought one.
360 Games with Gold continues to be great. I can see Microsoft reducing it to one game a month in the next year though. 360 support is supposed to be 'phased out' in 2016 and they will want to add more to the Xbox One's Live offering as its library grows.
Volgarr the Viking ($9.99 ERP): Available from Nov. 1-30 on Xbox One (note that Volgarr the Viking is only available in select territories – gamers in Germany, Russia, Korea, Japan, Taiwan, Australia, New Zealand and Brazil can look forward to the full version of Powerstar Golf instead!)
