If they released all the DlC's at 1 time the game wouldn't last as long if you spread them out the game will last longer and if you make mystery dlc's people are gona wana stay to find out what happens... It's logic dude use ur noggin F.Y.I. If you make all the stuff for every one then people won't buy the dlc's you have to make the dlc worth it it's like paying $10 for a candy bar(rip off)
