I'm considering to purchase TOW (PC) on the Official Private Division Store (https://store.privatedivision.com/the-outer-worlds/order). In what form (a key or an installer or what) the digital version is delivered?

I didn't buy it from there but I would guess a digital key sent by email that you have to use on the Epic store to download the game.

Check Greenman gaming. Good chance you’ll get the best price there. You get a key you claim within the Epic Launcher.

Thank you for the information.
