In regards to whether it's my turn or not, I'm waiting for Elf to go first, since she has more priority to move in my opinion, and Archer can't act until Lancer does.
I'll post after that happens.
And Xam, I've played Kingdom Hearts I and II and got through a good chunk of Chain of Memories, so if you need help at all, feel free to ask me.
I know some stuff about the rest of the series too through LPs and stuff, and any gaps in my memory I can refill through rewatching the cutscenes on Youtube, so don't hesitate to ask if you need help.
As for my input on Satoshi...
Satoshi is vastly overpowered. Overpowered can work by itself if it's justified- see the Arc example. But the way Satoshi is overpowered isn't quite the same as how Arc is overpowered though, which is part of the main problem here.
In fact, I'm going to use Arc as a basis of comparison. Yes, Arc is stronger than Satoshi, possibly even so when nerfed by the blood lust. However, she has other things to balance her out further- like OPOI mentioned, she has her head in the clouds most of the time. Plus whether she acts or not really depends on the situation. The other thing that makes Arc work in spite of her OPness however, is that she's not usually serious as a character. I don't mean in terms of personality, I mean in terms of how the story portrays her. It doesn't slam how powerful she is in our face constantly, so when she does go into action, we can tell the situation is a very serious one in order to provoke her into doing so. Plus there's more to Arc than her power, so much more.
Satoshi, like Mike mentioned, is the type that wants to solve everyone's problems. His power is a key part of who he is, to the point it distracts from who he is as a character. He's very much the typical hero character besides that. He does have weaknesses, but he doesn't have
enough weaknesses, so it makes the number of threats seem minimal. It makes it so he can pretty much solve everything with little hindrance, especially when so little can stop him. So when he goes around solving everyone's problems like magic, it disrupts both character dynamics and reduces conflict.
Conflict is key to making a story work- things become uninteresting without it. With how overpowered Satoshi is, he threatens to limit the level of conflicts. If he can solve pretty much all the problems in the story and everything is good and peaceful, then why have a story to begin with? If every enemy falls easily, there's little reason to be invested. Especially if Satoshi is taking over the fighting and problems solving for the other characters. Then you pretty much eliminate there being an RP in the first place, because it gives the rest of us nothing to do. And in an RP, you need to be considerate of the other players- you can't just do whatever you want, you need to think about them too.
You also need to not be so defensive when it comes to people's advice on this stuff. We aren't trying to attack you here. We're trying to help. Believe me, I'd love more feedback on my posts, because I feel like I have a lot to improve with my own writing. It's not an insult, trust me. Any writer that wants to soar to great heights in their profession needs to listen to the criticism they receive. Even if it is stated in a mean fashion, so long as there's anything that helps you improve in there, there's still something valuable to be gleaned from it, trust me. But in this case, I'm not trying to be mean. I'm trying to help. None of us are trying to be mean. So please don't treat us as if we are and treat our advice seriously.
