I think the only two ps4 games I have really played since the switch came out were Nier: Automata and Persona 5. They were great games. Nintendo has been really great though. Can't wait for dat Odyssey.
I am a day one owner of the PS4, a day one owner of the Switch, and a day one owner of the WiiU. I do not regret purchasing any of those systems on day one, however, ever since I got the Switch in March, I barely use the PS4.
I booted up my PS4 last night for the first time in 3 months. Only because NBA 2 k 18 was downloading. Couldn't play Splatoon or the download would stop, so PS4 it was.
I played the switch for a long time but now I'm giving my other Nintendo systems some much deserved love. Just finished Galaxy 2 last night, now I'm working on Xenoblade chronicles and sometimes fire emblem fates. I still pick up the switch though if I want to play Mario kart or splatoon 2.
