Four Swords is the most competitive co-op game I have ever played. It’s brutally fun, but you’re going to want to punch your friends in the throat after about 30 minutes.
To learn Kingdom Hearts lore going in blind you’d need an autistic kid who’s hyper-fixated on it, a couple cases of monster energy, and a weeks worth of LSD micro doses.
That should get you up to speed on about 50% of it.
Pokemon didn’t grow up with it’s player base. They try and keep the storylines Kid friendly, when I’d guess 70%+ of players are adults.
Black & White probably had the most “Adult” narratives of the series, delving into the slavery/forced labor a bit. I’d love to see the games delve into some more adult themes, but I doubt it will happen.
What needs to be remade? Nothing; I’d just like to see updated graphics, a couple tweaks in the story here and there, and maybe a few tweaks to the sphere grid.
It’s a great game, I just wouldn’t mind seeing it get upgraded a bit.
