played P5R and currently playing P4G and they both so goated actually
P5R is the best in terms of gameplay and graphics, it is so fun, it just oozes style, and it has so much to do in terms of content. Not only that but it has a amazing story and characters too that makes you feel like part of a family. Its overall a better experience and i actually did not want to finish at all because i was having so much fun. It has one of my favorite virtual words ive ever played and the vibe is so immaculate it makes me want to actually do more stuff irl lol
P4G i took a while to get hooked because it is a little more outdated gameplay-wise and has a different vibe but once i got hooked it has been such a amazing experience. The characters and story are even better than 5 and i actually cried halfway through the game because i got very attached to them and their story. I feel like its darker and choices have more of a weight on the story overall
Both games are very japanese so expect some cultural shocks but they are very charming and amazing in their own ways. Highly recommend and will catch P3 once i can too
