Possible pitfalls: The user might not realize they're violating the law. They could be looking for a way to play without buying again, but that's not feasible. I need to present this information clearly and respectfully, avoiding technical jargon but being precise.

Next, I need to explain the legal issues. Nintendo owns the intellectual property of Super Mario 3D World, so unauthorized distribution is a copyright violation. Users might not realize the seriousness, so it's important to highlight that downloading from untrusted sources can also be risky—malware, phishing, etc.

I should also address the community aspect. Emulation can help preserve games, but it must be done ethically. Providing links to download is out of the question. Instead, guide them to official stores or trusted retailers.

Additionally, some users might be unaware of other platforms where the game is available. Super Mario 3D World is on the Nintendo 3DS and Wii U, but the Switch can play some 3DS games via the Nintendo Switch Online service. Maybe pointing them towards those options if they don't have the Switch version yet.
