I agree completely about the costs
In the end I bought the various Rogues and Villains expansions - the shuttles, Falcon, Ghost etc. I have the base set and a couple of bigger ships, but I generally can't bring myself to pay the prices they're asking. Given the huge boxes they come in, it seems like I'm paying for air more than anything else
No idea about the gaming side of things or how well it's doing, but it doesn't seem to be high on FFG's todo list, especially with Star Wars legion just released/coming out.
