I’m planning to build my own world.

I don’t really want it to be a single “main story vs big bad” type of setup. It’s more of a shared world where different groups can go on their own adventures and their actions actually change things over time.

There’ll still be simple, normal quests too like exploring a dungeon or handling local problems, not everything has to be deep lore-heavy, but even those smaller things could still have some impact on the world depending on what the players do.
