Watch Deus Ex devs play and talk about their creation 15 years on

You always hear about how Deus Ex is one of the best games ever, but it's tough to say how an ambitious game will hold up 15 years later. Three key members of the game's development staff seem uncertain themselves when they start this Let's Play video, organized by the Deus Ex: Mankind Divided team at Square Enix.

Warren Spector, director and producer, Sheldon Pacotti, writer, and Chris Nordem, lead programmer and assistant director, take an hour-long tour through their creation in the video. Plenty of insights emerge as they play: from little details, like how the game does real-time lip syncing based on audio waveforms, to big plot differences, like how there was originally going to be a fourth ending.
