The above trailer for the upcoming PS4 Kingdom Hearts prequels and cinema stuff had like nine seconds of non-consecutive gameplay. Check me on it.
The second half of the video, however, shows almost entirely gameplay, with clips stretching out individually for five to ten seconds each. Much better. So the Kingdom Hearts III trailer does shit right. The II.8 prologue, not so much. I look forward to next year, when perhaps they'll play Silent Night over some story clips and try to scare us.
