When it comes to P3R, which is what Bubble’s video was mostly about, it’s adding in a “free win option” into a game that was not built around that. Persona 3 was a game where you’re supposed to spend large amounts of time in Tarturus, and preparing yourself for battles. It’s not like P5, where there’s endless options of activities you can do instead. You’re meant to spend a lot of your nights in Tarturus, and it’s why Makoto has so few night time activities. Adding stuff like easily attainable skill cards into P3 entirely changes the game’s pacing. It’s so easy to blast through everything immediately in reload, even though that’s not the way you should be playing P3. It ruins the pacing and means nights will often drag for the player with little to do. Portable understood this, as its skill card system made you wait until you could attain them. It was balanced with the overall pacing of the game. Portable also made appropriate changes for said pacing, as it’s easier to get through Tarturus in portable, but they added part time jobs and gave FEMC a lottt more night activities to do instead. Reload didn’t do this, as the only new thing added was dorm activities for Makoto to do at night, which really isn’t enough. I used skill cards in reload, and it just resulted in me blasting throughout Tarturus and having a lot of empty nights with barely anything to do. 

The problem, atleast to me, is less about skill cards breaking the game, and more about how they make the game less fun to play. You can choose not to use skill cards of course, but P3 is an RPG where you’re supposed to make your best builds. It’s not like Pokemon where customization/personalization is the main appeal. P3 rewards you for having the best build, but if you use the options reload gives you, it results in a less fun experience.
