The physical boxes for Riders of Rohan were produced by Warner Brothers. They were only delivered to Germany (German Version) and Great Britain (English). I never saw anything about a French version.
I suspect the reason Turbine did not discuss the situation with Riders of Rohan physical boxes is because it is something that is done by their owner Warner Brothers. Turbine does not have any input, control or information on the situation. Warner Brothers is most likely operating in a distributor role. All income and expenses are not part of Turbine's balance sheet. They are shown as being earned by the part of Warner Brothers that handles physical media for all Warner Brothers game development companies.
Unless stated otherwise, all content in this post is My Personal Opinion.
