20 Best Ever E3 Moments

After the Xbox One got off to an incredibly rough start for reasons we'll get into later, Microsoft began to rebound in the years that followed with a slew of consumer-friendly features, such as the launch of Xbox Game Pass and, perhaps best of all, a backwards compatibility program.

At Microsoft's 2015 E3 showcase, Phil Spencer revealed that a large number of Xbox 360 games would be playable on the Xbox One at no additional cost.

For digitally-owned copies they would auto-update, while physical games simply required inserting the disc to download the Xbox One-compatible version.

Better yet, these new versions benefitted from FPS and resolution boosts, and Microsoft also later added original Xbox games to the program.

This marked a major PR win for Microsoft, who were still struggling to recoil from the Xbox One's disastrous launch period, and made them seem especially pro-consumer given that Sony offered no such backwards compatibility for the PS4.
