Creator Backlash: Shigeru Miyamoto spoke out against GX in the years following its release, saying that it did nothing truly new with the franchise beyond adding new characters and tracks.
Fan Nickname: "Batman from Hell" for Black Shadow in some circles. Black Batman also works.
Given that Mr. EAD is essentially Mario, expect to see nicknames like Gay Mario, Fat Mario, and EADio.
Flip Flop of God: Deathborn's Evil Plan in GX gets this treatment within the game itself, possibly overlapping with Motive Decay. Is he going to destroy the universe or simply reign supreme over it? Story Mode suggests the former, his post-GP interviews say otherwise.
No Export for You: F-Zero X Expansion Kit, which was released for the 64 Disk Drive, an add-on that never made it outside Japan, either. Anyways, the Expansion Kit had new courses, a Car Editor (which was also in F-Zero GX), and a Course Editor.
There's also F-Zero Climax, which also had a level editor. A partial translation for it is available.
The two BS titles are this by default, as the Satellaview was an add-on for the Super Famicom.
Recursive Adaptation: F-Zero: Legend of Falcon inspired the F-Zero: GP Legend GBA game (it's also called Falcon Densetsuin Japan). Yep, Ryu/Rick's there.
