The Source 2 engine happens to be the successor to the original Source engine, which first made an appearance more than a decade ago with the launch of Counter-Strike: Source. Games that used to run using the original Source engine would comprise of Valve classics such as Half-Life 2 and the Left 4 Dead series, in addition to other third-party and independent releases including Garry’s Mod, Dear Esther, The Stanley Parable and Titanfall.
Jay Stelly of Valve shared, “With Source 2, our focus is increasing creator productivity. Given how important user generated content is becoming, Source 2 is designed not just for the professional developer, but enabling gamers themselves to participate in the creation and development of their favorite games.” Hopefully this will result in more developers jumping aboard the Source 2 bandwagon and churning out some A class titles in the future.
