Mario Kart: Super Circuit Classic
The Matrix has 113 racing games on file for the Game Boy Advance, released between 2001–2007. 67 of them support multiplayer, including 1 with co-op. They're ranked below by legacy score, so the games that shaped the genre on the GBA come first, with lesser-known picks further down.
Racing games range from realistic driving to kart racers with weapons and shortcuts. Races are short, making them great for quick sessions and split-screen rivalries.
Typical commitment: quick session (under an hour, or endless arcade fun). Tip: Learn each track's racing line and braking points; in kart racers, item strategy matters as much as driving.
