I do agree that practice would be shitty and I'm not trying to call you out, but is there an example of any game that has ever not outlined what would be included in the season pass before putting it up for sale?
I feel like there's a lot of season passes that do so. Didn't Fallout 4's season pass do exactly that? And even if they give you names of DLC, they don't necessarily tell you how large or expansive this content is. There's a big difference in value (I know value is subjective) between Automatron and Far Harbor for example.
To be fair, I think the outrage over Season Passes is overblown. People should just be smart consumers or show some restraint in their purchases. But in the scenario I outlined I can see how forking over cash for content not yet detailed can be problematic. But still, if people would just wait and read reviews they could assess if the value of the content is worth the price of the season pass.
SFV, for all the shit it gets, did it right. It tells you what's included on the PS Store. Of course, that doesn't stop people from apparently buying something without reading the paragraph of text on the store page explaining what the pass contains.
How long have season passes been around at this point? I feel people are being intentionally obtuse if they don't know by now what a "season pass" includes. Everyone who's moderately involved in gaming as a hobby should know by now that a season pass doesn't mean all DLC and crying "but it's called a SEASON pass!" is no longer an excuse.
