My friends sure did. Personally I never gave a damn about rock band or any other music rhythm games. You're not long though.

I also like to point out that train SIM DLCs, which I also don't play or care about, are also exorbitant and insanely numerous. But that's a really niche product and I've heard the argument made that they're trying to recoup off of the investment for something that gets low numbers of sales. I don't know how much work goes into developing one fucking train car or one train or whatever; it would seem to me that most of it should just be assets considering that the physics engine and basic architecture of all components is done and basically similar. Regardless of it's statistics a train engine is a train engine and all cars look basically the same; standardized wheel frame with one of a fairly small number of actual car designs. I think it's like a dozen or two? Everything after that is scaling and skin, and changing numbers for a scale isn't that hard. I don't even know if these things have hit boxes, since it's just meant to be a train sim and not something you run around on like a platformer. So whatever the cost of developing the skin assets is most of what those DLCs are, so charging like 15 bucks for each them is pretty ridiculous. Honestly I don't even know why I looked into this in the first place years ago but the pricing structure really is silly.
