So, I have both Mario Odyssey for the Switch and Assassins Creed Origin for the PS4 on pre-order. Today I found out that they're released on the same day!! I had a minor freak out but I think I have a working solution: Play Mario Odyssey on the Switch in hand held mode (play most of my switch games this way so the kids can have the tv for ps4 while I'm playing) When the battery goes flat put it on recharge - and play Assassins Creed Origin on the PS4 (after I've kicked the kids off it)
