Indeed, very few people I know that still follow South Park at all. That being said, the WoW episode is legendary, so with similar content it could be good.
I saw something Southparkish in a shop today. since I was in a hurry I don't remember anymore if it was a calendar or a book.
So at least I can say that they are still selling merchandise for it here.
When look in the image of their reflection first what came to my mind was about lotr , I also don't think it will be something good but I am curious to see what they will be able to make about it in terms of rpg like party based one, and lack of variety of enemy seem not existent, counting how many abominations are in the imagination land. And hopefully not final fantasy style like it was with super mario rpg.
