Saw this from an employee at GS on reddit:
Gamestop employee here. This is how it should work for every store:
On 11/14/13 gamestop will start processing pickup numbers at 6pm. Once you get a number do not lose that ticket, or you're going to make it hard on the store. As that ticket is your system.
Most games are coming out on 11/12/13 and can be picked up then (which we suggest as it's less we will have to worry about come the midnight launch).
Once you get a ticket you are welcome to stay and play the demo ps4 (most stores are getting them this week and next (if they are getting one)). Or you are more then welcome to come back later in the evening, you do not have to stay the entire night. Your ticketed number is your place in line.
Again do not lose that ticket.
Non reservation customers will be process in a first come first serve order. I do not know how many extra, if any, stores are getting. But Sony has been very adamant about having some for walk ins.
If you have any more questions let me know or join us over at
