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. Crystal Dynamics' live-service game suffered from repetitive missions and predatory cosmetic pricing, leading to a 70% drop in players within its first month, far worse than the typical triple-A launch. The underwhelming endgame content and lack of meaningful updates made it slower to improve than #5 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.
