For Polygon's E3 2014 Editors' Choice Awards, we followed these guidelines: first, games must be in a playable state, though this could be in the form of a "behind closed doors" demo, which are builds of titles not available for play to E3 attendees; second, this must be the first time a game is playable at E3 — meaning games we've previously acknowledged with our Editors' Choice picks are ineligible.
