CS:GO uses similiar tactic. And yes, those DLC cost way too much. It's good to have that Witcher 3 though, when you get lots of them for free. There are only 2 with story that need to be bought, but they are cheap as hell, not unlike EA's costs that make you pay twice as much of the game costs, to get DLC and a shiny knife with some priviliges, like faster game queues...
