Play Triathron, The (Japan) Online

Triathron is one of those weird, Japan-only NES sports games that somehow makes swimming, biking, and running feel both frantic and slightly janky. You're mashing buttons to keep your little athlete moving, switching between events with that classic NES stiffness—like your guy’s joints are made of wood. The swimming part’s the hardest for me; the controls just don’t want to cooperate, and I always end up flailing in last place. But there’s something oddly satisfying about how rough it all feels, like you’re fighting the game itself as much as the other racers. If you’re into obscure retro sports titles, this one’s a quirky time capsule.
