I've noticed people are posting quite a few topics about the game Hearthstone in the WoW subforum. I think it would be nice to have Hearthstone as a separate sub forum. This would allow people to talk about different decks, goblins vs gnomes, and so much more without it getting cluttered into the wrong game.
Well its not really an RPG. Its a card based strategy game. But your right about it being popular. In my opinion it should just be discussed in a general gaming section. Maybe the admin will add a section for it anyway though.
Well, technically Hearthstone is an MMORPG game since you use characters to play online, though you don't follow a story. A section for it would be nice.
