Actually two questions. One, you mentioned a "Season pass" in the product description on the sales page, but there's no mention of what that is.
Second, is it possible to change a Steam license to a standalone? Just wondering, as I get mildly annoyed by waiting for the Steam client every time I run the program. Also, I'd like to be able to double-click on a Qubicle model to launch the app, and the Steam version yells if you do that.
