Nights is one of the most addictive games I've ever played. I forgot it was on the PS3 to be honest. How does it play with the dualshock controller? It's one of those games I can't imagine playing on anything other than the Saturn's 3D pad. That said, they really need to bundle it with Christmas Nights and re-release it on modern platforms. I'd love a Switch release. The Sega Ages stuff on Switch is great, but I can't believe they haven't given us Nights, Virtua Fighter 2, Sega Rally or Daytona USA yet.
Persona 4 is one of the greatest RPGs of all time. To be honest, I've been meaning to play through it again some time too. It's way better than Persona 5 too... I appreciate what they did with the dungeon designs (taken mostly from Tokyo Mirage Sessions FE), but the game just got so bloated and I didn't find a lot of the characters particularly likeable. I much preferred the story and characters in 4.
