According to some of the reviews quite a fair few small things have changed. I'm pretty sure I noticed something different in the intro sequence. Of course these games take a while to get into, after a couple hours I'm still in the early setup parts. The biggest change I read was apparently to combat. There are supposedly some balancing changes and guns have changed. I'll find all that out later. I'm bummed at why it couldn't be DLC or something to the original but I guess if they've changed a lot then it makes sense. There is also an extra semester on the end too.I'd be interested to hear your thoughts throughout your playthrough on the differences between Royal and the original Persona 5. From what I've read they don't seem to be massive changes but would like to know how it plays compared to the original. I'm tempted to go and get it because I loved the original but not sure if I can justify paying full price if there are just small differences.
