Screenshot from my gameplay of WarioWare, Inc.: Mega Microgame$! on the Game Boy Advance via Nintendo Switch Online (Nintendo Switch Online + Expansion Pack subscription is required to play this).

Also, as this game came out in 2003, I didn't know about this game back in the day until around 2010 when I played Super Smash Bros. Brawl on the Wii. This is how I first got introduced to the WarioWare series. The first game I played was WarioWare: Snapped! on the Nintendo DSi.

And I was only around 4 years old at that time. I'm familiar with Pokémon Ruby and Sapphire as that game came out at that time (for the North American release here in the U.S. on March 19, 2003).
