Stellaris playsets and load order: a practical guide

This guide is for anyone who has added a handful of Stellaris mods and wants them to behave, rather than fight each other. By the end you will know how playsets group your mods in the Paradox launcher, why the order you put them in matters, and how to test a list properly before you sink dozens of hours into a new game.

What a playset actually is

A playset is simply a saved collection of mods inside the Paradox launcher. Instead of ticking boxes every time you start Stellaris, you build a list once, give it a name, and switch to it whenever you want that combination active.

Most players end up with more than one playset. You might keep a light one for a quick game with a couple of quality-of-life mods, and a heavier one for a full overhaul campaign. Playsets let you swap between these without rebuilding the list from scratch each time.

Why load order matters

When two mods try to change the same file, the game does not blend them. It takes whichever version loads last and applies that. This is the whole point of load order: it decides which mod wins when there is a clash.

This matters most with overhaul mods, UI changes, and anything that touches core game files. A small content mod that just adds a few events rarely causes trouble. A mod that rewrites large chunks of the game’s files is far more likely to collide with something else in your list.

Setting your load order

There is no universal correct order for every combination, because it depends entirely on which mods you have and what each one touches. That said, the general process in the launcher follows the same pattern.

Open the Paradox launcher and select or create the playset you want to work on.
Add each mod you want active to that playset.
Arrange the list so mods that should take priority sit lower in the order, since later entries override earlier ones for shared files.
Save the playset once the order looks right.
Launch the game and check that the mods you expect to see are actually active and behaving as described.

If the launcher flags a conflict or shows a warning icon next to a mod, do not ignore it. It is telling you two or more mods are touching the same thing, and your order choice decides the outcome.

Check the mod’s own page first

Before you guess at an order, look at the mod’s own page. Authors who know their mod will clash with something common, or who depend on another mod to work properly, usually say so directly. You will often see instructions such as needing to sit above or below another specific mod, or requiring a particular mod to be present at all.

Treat these notes as instructions, not suggestions. A mod built to load after another specific mod will often break, or quietly fail to apply its changes, if you place it the wrong way round. When a mod page gives you a load-order requirement, follow it exactly rather than trusting your own instinct.

Test before a long game

Back up your save files before you start experimenting with a new playset. It costs nothing and means a bad mod combination never puts an existing campaign at risk.

Once your order is set, start a short test game rather than committing straight to a long one. Play far enough to see the mods you added actually working: new events firing, new buildings appearing, UI changes showing up correctly. A problem that only shows up after several hours is far more annoying to track down than one you catch in the first short session.

If you play in multiplayer, remember that mods need to match between players, and that some mods are flagged by their authors as unsuitable for online play. Stick to singleplayer testing for anything you are not certain about.

If something goes wrong

If the game crashes on launch or in the early game, go back to the launcher and disable the most recently added mod first. Restart and see if the problem clears.

If that does not fix it, disable mods one at a time, testing after each change, until you find the one causing trouble. Then check that mod’s page again for any load-order note you might have missed.

Removing a mod from a playset does not delete anything from your existing saves, but content from that mod may vanish or behave oddly in a save that already relied on it. If you need to return to a clean state, switch to a playset with no mods active and confirm the base game still runs properly before rebuilding your list.

Keep a short note of which mods sit where in your working playsets. It takes a minute and saves a lot of guesswork the next time you need to add or remove something.
