FIFA is a major game franchise, offering thousands of hours worth of content gamers enjoy around the world through yearly releases. Many were happy to see the soccer/football game finally get announced for Nintendo after years of ignoring the system through FIFA for Switch.
Little was known about it when announced during Nintendo’s Switch Conference but EA is ready to explain a little about this version of the game. It is indeed a version of the upcoming FIFA 2018 NOT a port of an older FIFA. That is great news alone and similar to NBA 2K18 it’s releasing alongside the other versions.

“Well, as we have said, we are custom-building a FIFA version for the Nintendo Switch,” Moore said of the game. “It will be FIFA 18, and it will obviously be later this year when FIFA 18 comes out.”
Of course it was always going to be FIFA 18, but this is the first time that someone has confirmed as much, as well as suggesting a release window beyond simply “2017”.
“And I look forward to seeing the Nintendo Switch,” Moore went on, “we are not far away from its launch and in fact, here in Paris, I was very impressed to see FNAC stores with Nintendo Switch in the windows.”\
