Hiya!
Well, for PS4 I have Monster Hunter World, Destiny 2 (only 1 is recommended though), COD WW2, Battlefield 1 & 4, Future Tone, Journey, and a few free games. I've only had the PS4 for less than a year so I'm still trying to expand my collection (switched from XBONE).
On the 3DS, way too many to list, but my top few nowadays are ACNL, Project DX, Pokemon Y, and many many more. (Like literally, at least 50, and a majority I haven't started yet).
Unfortunately, no Switch console yet :c
What do you have on PS4?
