Ah, the joy of Censorship. More specifically the joy of a broken ratings system.
In Australia we don’t have a rating for Mature Games, and so we simply miss out on any games that are rated as such. There are plans to fix this, but they move slowly, and there are always those who oppose such things, which slows the process down even more.
So, for now, we can’t get Walking Dead on consoles here.
I feel so much safer.
