One of those big collections for sale right now is by a player from our store.
He has a baby on the way in November. Our store shifted the night to Friday nights and he can't make Fridays. Plus he play a lot of Marvel Dicemasters. So he made the decision to focus on Dicemasters.
Lost another player about 3 months ago who said X-wing was his 2nd game and he was quitting because the new waves were actually coming out too fast and he was annoyed that before a wave was out people were already working on the meta for how to beat it with the next wave.
