Elden Ring: Nightreign, a $40 standalone multiplayer spinoff, was the best-selling game in the U.S. in June 2025. It outsold Mario Kart World, Nintendo’s flagship Switch 2 launch title, despite the latter's massive promotion and bundled console deal. Nightreign launched at the end of May and quickly gained traction with strong reviews and 3.5 million sales in its first five days. #eldenring #gaming #eldenringnightreign #mariokart #nintendo
