Do you have to buy a game again if you buy it in Epic Games?

As I said at the headline. I would like to know if I have an Epic Games account and bought a game and I now buy a new laptop, I have to buy the game again or not

Nope, you can just log in to the Epic Games account on Laptop.

No they are stored in the account. Basically, you can log in to any Epic PC and download and play the games you have bought.

Incidentally, this is also the case with every other launcher and also with consoles.
