Reloaded in general is a waste imo. Good game in isolation but, as you may have figured out, the key problem with Persona 3 is that there are too many different versions without one being definitive. You have Persona 3 FES with better visuals and exploration gameplay, but less content, but has the epilogue to the story. And then you have Persona 3 Portable, which has way more content and quality of life updates, but doesn't have The Answer epilogue and the exploration is point and click. Which one do you choose?
All Reloaded does is take those two and give you a third, more expensive option which is kinda more definitive but also completely different to the other two in some ways. Can be safely ignored. It doesn't even wrap up a plot point that has been left open in 3 and continued in future sequel games, so ifor the price point, pay it no mind imo.
