Yes the PC can run Halo 2 (in a theoretical dream of Luke's atleast where Microsoft isnt a penis) but can it order pizza by yelling at it. Probably if you can code.
BUT if you cannot code and have a ton of wads of cashez to spend on $70 games that runs on lower spec than you may want an Xbox one for the job.
Dominos recently joined up with microsoft to brink those people across the pond and Xbox one dominos app that can order pizza with a voice gesture as if your phone was way to far away and you need all that 3 minutes in between halo matchmaking lobies to adjust you loadouts.
You can even snap the Dominos app with your gameplay so you can track your pizza while you have sex with other online players' mothers. WHAT THE HELL HAVE WE COME TO.
The USA already has a similar app form pizza hut.
