Once a mobile gaming behemoth, Angry Birds collapsed from over-saturation, greed-driven microtransactions, bad strategic choices, and intense competition. Originally a worldwide hit, Rovio alienated devoted gamers by diluting its brand with too many spin-offs and switching to pay-to- win models. Rivals like Candy Crush and Fortnite overwhelmed its understated gameplay. The 2016 Angry Birds Movie lacked appeal, and removing the original game from 2023 infuriated many. Along with financial hardships, these mistakes caused Rovio to fall and finally be sold to Sega. The collapse of Angry Birds emphasizes the dangers of giving short-term gains top priority over player allegiance and creativity.
