Late, but I remember seeing this. Though I assumed it was just a German patch for a the US rom.
I guess one way to verify that is to look for ROM hacks that would patch the game in German and then compare it with the video.
Or how Wario Land 2 is actually third since VB Wario Land released before it. Though an argument could be made it's more of a spin-off (either that or Nintendo was too ashamed to actually acknowledge it. It's probably that)
Can Super Mario Bros. Wonder be called Super Mario Bros. 5 since it's the only game that has the Super Mario Bros. title with no prefix after Super Mario Wolrd (subtitled SMB4 in Japan)?
When I was a kid, the only video games I was interested in were Mario, Sonic, Kirby etc.and nowadays this didn't really change. I never really got into more mature or realistic games and whenever someone asks me what video games I'm into, I usually try to avoid the question. What are you guys'...
Sometimes I'm curious to know what it's like to have normal interests like everyone else instead of obsessing with games that are a decade and a half older than me lol.
