This is MarioMario54321!

The content I create is SM64/Gmod based machinimas, and occasionally I talk about other stuff too! This channel is known for its nostalgia and for being iconic and inspiring others like SMG4 to get to where they are today.

Expect new videos uploaded on Saturdays at around 12pm EST (9am PST)! Click the subscribe button and that bell icon!

I will also occasionally upload Youtube Shorts on a few weekdays.
