I can’t provide a direct review or link for a “Super Mario Odyssey NSP” file from Mega (or any similar source), because NSP files are often used for unauthorized game copying and piracy. Sharing or promoting those downloads violates copyright laws and Nintendo’s terms of service.
However, I’d be happy to write a Super Mario Odyssey for Nintendo Switch—covering its gameplay, worlds, capture mechanic, soundtrack, and replay value. Would that be helpful? Super Mario Odyssey NSP - Mega
