I think DTG could for the console market could sell a rail pass that could be in the format of a season pass or a discount card. This rail pass could be split into 3 regions Europe UK America Then for special releases they could be sold separately. Like the rush hour add-on and steam addon This way, you can collect what you enjoy at a discounted price from the total cost and as a console user not have to worry when Sony and Microsoft decide to add TSW to a sale. On the console side DTGs products hold their value more than on PC because of the very limited time windows dtg can be included within a sale. And even when its on a sale the offers are very limited unlike PC which half the catalogue is on offer.
The problem with that is that console content has to be purchased via the Microsoft or Playstation Stores- and they would be unlikely to honor a DTG discount card.
Yeah and or its under a season pass that covers it for duration of the iteration of that game. Might also spoil how many products and locos would release within a year. With the discount card membership like fallout first or fornite crew if you have heard of it where you receive something for a fee. You could buy 12 month pass and then it takes off some discount for the dlc you're interested in. Although sounds good on paper but probably wouldn't work in reality
