The Know also uses vgcharz numbers every once in a while.But since you can see the numbers free of charge, and is simply information about another product, I think there is no problem.I mean, if that was the case, every time a video were to use a sales number from an official source, do they need to ask for permission to the companie?Since thats not the case, i guess you could apply the same to here.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
