I'm going to take a big pass on Persona 5. I do love RPGs, and I understand the appeal of P5, but think it would get tedious to me well before the end of the game.
HZD on the other hand is definitely one I will pick up eventually. I'm picking up Final Fantasy 12 and World of Final Fantasy already, tho, and don't want to get in the habit of buying a bunch of epic games without beating them... So I'm going to wait til I beat those before I buy more games like HZD.
Rocket League is a great suggestion. I almost forgot about it, but remember all the hype it had for quite awhile after it first came out, and I think it's exactly what I'm looking for. Some games we can digest in small bites between sessions on our RPGs.
I think I might pick up No Man's Sky too... Probably going to be really cheap in the used section by this point I bet.
