Apparently, stores were closed based purely on profit rather than location. Hence some areas seeing multiple stores in close proximity remain open, while others saw their only store close.
The new administrators didn't have time to look at the specifics of each store; they likely looked at a big list of all of them, and how money they make, and closed stores that didn't meet a specific number.
What this doesn't take into account is that if there are two extremely profitable stores right next to each other, closing one of them is still more financially viable than closing down a moderately profitable store in a town on it's own, as all the customers from the closed store would just go next door (or nearby, whatever).
Chances are a buyer will likely make further store cuts, as they'll be more selective when determining which stores they want, so they aren't going to want stores too close to each other.
The Gamestation store I work at survived. But all the staff are still really down, as we know that we're not in the clear; this is just the first round of cuts. There's a GAME very close to us, so we could be closed by either a buyer, or upon liquidation if no buyer comes forward.
We're also down because we have to deal with angry customers who can't use their gift cards.
