In the world of console video games, Microsoft, Sony and Nintendo stand as titans. For PC gamers, however, Valve reigns supreme. Its distribution platform, Steam, may not be the only place to buy and play games on the PC, but it's easily among the largest, oldest and most iconic. Today marks Steam's 20th anniversary.
Valve is celebrating by slashing prices on its self-published games, offering most of its catalog for 90 percent off, except Half-Life: Alyx. The sale's landing page doubles as a cheery retrospective of Steam's last two decades. It's a fun read that offers users the chance to buy the "Top Games" from key years in the platform's history, punctuating footnotes about the very first Steam Sale with a chance to buy the original Portal for just $0.99.
