Marvel's Avengers

Marvel's Avengers squandered the most valuable IP in entertainment with over $200 million in losses for Square Enix before support ended in 2023. The underwhelming endgame content and lack of meaningful updates made it slower to improve than LawBreakers, which at least offered a complete experience at a lower price. Ultimately, its failure cost over $200 million, making it one of the most expensive flops in gaming history.
