You Want to Pre-Load FIFA 18
If you want to play FIFA 18 as soon as possible and you are OK buying the game digitally, you should pre-order FIFA 18 within at least 5 days of the release date.
This will allow you to start the FIFA 18 download without joining EA Access or Origin Access. The FIFA 18 download will likely be 30GB or so, which will take a while to download on day one.
If you plan to play at a midnight FIFA 18 release, this is the only real option since most stores are not planning to be open. By pre-ordering, even a few days early, you will be able to make sure that you get the game downloaded in time and installed so you are ready to play.
This works on digital copies sold through Microsoft, Sony and Origin. You may not be able to pre-load digital copies purchased at GameStop or Amazon.
