I finished Persona 3 Reload last month. I thought it was definitely not as good as Persona 5 (which I still have a fair bit of complains about).
The gameplay loop itself felt much staler than Persona 5’s mostly because of Tartarus. Plus there is that overall weirdness around how the male protagonist is someone who all the female social links “depend on”. I read that this weird aspect has in fact been toned down from the original game where unless you decide to involve yourself in a romantic relationship with the female social links, you can’t max then which… I don’t know what to say about it.
The soundtrack was really good though especially the songs with lyrics in them. Whenever I listen to “Color Your Night” I get close to breaking a tear for personal reasons. I think everyone should listen to “Color Your Night” and “Full Moon Full Night” since they are objectively good songs.
Overall I expected it to be much worse than Persona 5 but it turned out to be not as bad as I had expected.
