Didn't clear your schedule to track E3? Here are 40 plus PC game trailers from the event along with expected release dates and launch platforms for each title. The games are ordered alphabetically and if they are due to appear on both generations (Xbox 360/PlayStation 3 and Xbox One/PlayStation 4), then we generically labeled them as Xbox and PlayStation games to reduce clutter. We crosschecked our list with several sources but we're bound to have missed a few titles so feel free to share those in the comments.
