Yeah there is, stop being such a corpo slave to steam.
This isn't about Steam. It's about owning all your games on one account. If itch.io is your main storefront, that's fair. Some use GOG, others use Steam etc.
but who cares about weird brand loyalty
literally just get the game here and add it to your steam library
Not the same thing. It doesn't add a license to your account, so you still wouldn't own it on Steam.
why does that matter tho? you still own the game and you can still press the little green button on steam to play the game, jesus
