Persona 3 Reload
Overall, I'd say that Persona 3 is still a bit harder than its sequels, despite the new additions that Reload brings to the table. For example, it has a few consecutive boss fights, where you don't have the ability to save in between. And some of the instakill attacks can really ruin your day if they hit the protagonist, since that means game over. This was addressed in later titles, by making your party members take a lethal hit for you, if their social links were high enough. But Reload didn't add that, so you're stuck with the old clunky, mechanics.
Another minor annoyance is that you don't earn any money from simply winning fights. Instead, you have to deliberately pick the "coin" card in the post-battle mini game, if you're lucky enough that it appears (random chance). This is unique to P3, and the devs thankfully changed it for the later games. Of course, money can be earned by selling loot, but that just makes the game even more grind heavy. I had hoped that this was addressed for Reload, but alas, no such luck.
On the flip side, I really like how this game expects you to strike a balance between improving your social links and participating in combat. If you focus on just one of those areas and neglect the other, things will get a lot harder, so you need to manage your free time wisely. I also appreciate the new nighttime activities that were added for Reload, which make raising your stats a bit easier. This allows you to pass the checks for starting certain social links a bit sooner, which can be quite helpful.
Another great addition is that all social links are now fully voiced. Don't get me wrong, the writers did a great job here, it's just that everything feels even better now that the words are actually spoken. Lastly, Reload adds new downtime activities that you can do together with your party members. Stuff like reading books, watching DVDs, cooking or gardening. These little moments give more depth to those characters, revealing some info that was either only hinted or never mentioned at all in the original game. It's a really nice addition.
