HELLO OKAY if you want slow games, I can talk to you about slow games--

monadexe is a horror game about the afterlife! The catch is that everything in this afterlife is messed up and keeps messing up. Characters keep their powers, though using them could cause the world to mess up even more. AC is a points-based system (so you earn points for doing different things, like making posts, or tagging new characters, etc.), which-- I think looks more confusing than it actually is, haha. Fortunately, the mods keep track of AC for you, so it's not too much work! The mods are also super involved and tailor a lot of things to your character, making each character's situation, both during events and outside of them, pretty unique! There are no castmates there, unfortunately, but the pace might be your thing.

Or! synodiporia might be your jam. I don't play there currently but I was there for a long while, and the pace has always been pretty chill. It's basically about characters traveling to different worlds to "fix" or change things. Visiting these different worlds gives you the option of having your character retain their memories or being AU'd into that world. You can be as involved or uninvolved in the events as you want to be, and because each world visit lasts a few weeks, it's really not hard to keep up with developments, I think! AC is thirty comments, which might be a bit steep, depending on your definition of easy, but you can link as many threads as you need to reach the total so that helps to balance it out a little. There's a couple Fire Emblems and SMTs there, as far as castmates go, but because characters have to figure out the goal in each world, Joseph could probably make decent use of his Stand there!

Also, this is the part where I admit I've been itching to try my hand at Caesar and I'm looking for the same things you are SO IF YOU DO END UP TAKING JOJO SOMEWHERE... WINK WINK...
