Valve's Steam has dominated the PC gaming market for nearly two decades, despite various attempts by companies like Amazon to challenge its supremacy. Ethan Evans, former VP of Prime Gaming at Amazon, shared insights on their unsuccessful efforts to disrupt Steam, which included acquiring Reflexive Entertainment, developing a PC game store leveraging Twitch, and launching the Luna game streaming service. Other major publishers such as EA, Ubisoft, and Bethesda also failed to establish competitive storefronts. The Epic Games Store, launched in 2017, has not positioned itself as a true rival to Steam. Evans noted that Amazon underestimated the reasons consumers use Steam, which combines a store, social network, library, and trophy case. Despite criticisms of Steam, its ecosystem and features have reinforced its dominance, while alternatives have struggled to gain traction.
