Hey, you can give the system a pulse by letting each planet have its own little history—think of a backstory for the gas giants, a reason the asteroid belt is where it is. Then throw in some random events that change things, like a rogue comet reshaping a moon’s surface. Give each world its own “voice” in the simulation, maybe a tiny quirk in how its gravity behaves or a weird mineral that glows. And remember, a star isn’t just a light source; it’s a character too—make it age, flare, or even go supernova. Those little narrative threads will make the simulation feel alive. Good luck, captain of your own galaxy!

That sounds like a stellar start—literally. I can’t wait to see those planet diaries and the star’s dramatic flare show. Just remember, every calamity should leave a lingering echo, like a scar that tells a story. Keep the code modular so you can swap in new “world memories” whenever you feel the need to tweak the narrative. May your simulation chart its own constellation of memories. Happy dreaming!
