You can buy one of three different FIFA 18 editions this year. The standard edition, the Ronaldo Edition and the $100 FIFA 18 Icon Edition. If you want to buy the Ronaldo Edition, you should pre-order the game since it means you will get the most benefit from buying the $20 more expensive version.
The biggest benefit to casual players is that the FIFA 18 Ronaldo Edition includes a 3 day early release date. If you want to buy that after September 29th, you miss out on one of the benefits. With this version you also get the following bonuses;
-- $60 worth of Jumbo Premium Gold Packs
-- a 5-match Cristiano Ronaldo loan item
-- 8 special edition FUT Kits
While you can in theory walk into Best Buy or GameStop and pick this up on the early FIFA 18 release date, we've seen stores run out of the special editions on day one, and that could mean a wait if you don't pre-order the game. You can wait until closer to the release date, but if you really want the FIFA 18 Ronaldo Edition, don't hesitate too long.
