- So, the whole game is basically people playing the old WoW tcg in an inn?
- Yes, and the players are all tired, drunk player characters looking to kill the time between log ins of their players.
- You can find a 'game' (specifically a Garrosh vs. Jaina game) being played at the main hubs for Alliance and Horde in the Vale of Eternal Blossoms, so this is confirmed. Not so much for the old WoW TCG though.
Luckily, some clever guy had a wonderful idea to dispel this threat, and make some coin wile they're at it. To occupy the heroes' time, he invent an addicting card game and gave away the basic set to all of the old heroes. That way, the adventurers can channel the OCD normally reserved for gathering arbitrary numbers of random objects into something harmless, yet profitable.
My evidence for this? First, a heartwarming promotional image◊ that shows kids from both Horde and Alliance races (as well as a Merloc) gathering around to play a game of Hearthstone.
Second, the fact that it's called "Heroes of Warcraft", in spite of villains like Gul'dan and Garrosh being class representatives, and the fact that all kinds of nasty guys can be summoned as minions. My theory is that the "Heroes of Warcraft" subtitle doesn't refer to the characters in the card game, but rather the characters the players are actually playing as; retired adventurers.
- This theory is gathering strength, with the flavor for The Grand Tournament mentioning that the titular Tournament is actually the old Argent Tournament from Wrath of the Lich King, having changed over some period of time into a sort of good-will sporting event a la The Olympics
And you know what? That's actually a pretty good plan.
- Considering how WoW is already the most-popular and highest-grossing MMORPG of all time, with something like 10 million currently-active players (which is below its high point, mind you) you've probably got it exactly backwards - they made it a Warcraft game to sell it to the WoW players.
- More likely, it's an attempt to keep WoW's money train rolling. WoW has been around so long that anyone who is capable of having their fill of generic gameplay already has. The game's population spikes whenever a new expansion comes out, then peters out over the next few months. At this point, the game's unheard-of longevity is its biggest barrier to remaining relevant. Hence, Hearthstone is a way to harness the WoW IP and use it to start a new IP before the eventual day that WoW itself is no longer worth active development.
- Almost certainly Jossed as of Knights of the Frozen Throne, where Death Knight did appear as its own class, but only as overpowered uncollectible cards.
