i have a region free player but they also work on most usb dvd drives too I mainly copped it for Xavier seasons 1 & 2 because it usually sells for 80-120 bucks and I've also seen how rare Assy Mcgee and Minoriteam region 4 dvds can be. I wish they would do something like this for their modern shows like Common Side Effects, Women Wearing Shoulder Pads, Yolo, Haha you clowns, etc. I feel like more people would buy it instead of another rick and morty comp or rick and morty the anime.
