We already covered some more general information about Dragon Quest XI recently. Now, we will compile some trailers and videos we have found showing some gameplay for the game. There are some trailers that compare the 3DS portable version to the much more graphically intensive PS4 version. Afterwards, there are other videos featuring some unedited gameplay. The videos themselves speak louder than me describing them, so go ahead and give them a watch below.
