Here is my reply to NZGameshop/OZGameshop:
Hi NZG,
It is not a problem with steam at all. It's a problem with the game itself and how badly written the code of said game is, of which the responsibility sits current with Warner Brothers who are the publisher.
I understand that RockSteady games outsourced their PC port to a company called Iron Galaxy, but it's been published and released to the public by Warner Brothers in a broken state.
I am unable to play the game in it's current state as it repeatedly locks up, stutters to the point of being unplayable, sound cuts in and out etc etc...It's a defective product that I have purchased from you.
If I had purchased from you, say a Collectible Figure, and it arrived half broken and it wasn't the couriers fault but the manufacturer sent them out in this state it wouldn't be acceptable, nor is it acceptable to do this with software.
I understand that you are stuck between a rock and a hard place, but as the retailer you have more power to push back on Warner Brothers than I am. As I'm sure you are aware, this isn't a 'your computer isn't up to spec' issue, it's software that has been release knowingly in a broken state. I hope that you push back against Warner Brothers over this for the sake of your loyal customers.
Cheers,
