Let’s rewind to the reveal. Nintendo fans were starved. The Wii U had been a graveyard for serious sports titles. When EA announced FIFA 18 for the Switch, the wording was careful. It wasn't a port of the PS4/Xbox One "Frostbite" version, nor was it the mobile "FIFA Mobile" garbage. It was a custom build using the Ignite Engine (the engine used for FIFA 17 on PS4/Xbox One).
The launch version was a miracle of compression. It ran at a steady 60fps in handheld mode. It had The Journey (the story mode). It had Ultimate Team. It was, for all intents and purposes, "real FIFA."
But then the updates started rolling out. And the FIFA 18 ROM update (Title ID: 0100B9E00425A800 for the curious) is where the story gets dark.
