I don't care about Hearthstone, Overwatch, or Heroes of the Storm.
Given how both the core Blizzard audience and Blizzard itself treats these games, neither do they. Therefore I haven't paid any attention to their announcements.
Warcraft matters. Starcraft matters. Diablo matters. Those three IPs sit on top--control the Network Effect for--their respective niches (MMO, RTS, ARPG) Everything else does not because it does not (CounterStrike, League of Legends, Magic- those three rule the Effects in those niches).
I implore you--Vidya and Tabletop alike--to stop being fucking retarded faggots about this. You want to know why Blizzard and WOTC signed that deal allying together?
NETWORK EFFECTS, MOTHERFUCKER!
Each recognizes the other as the dominant Network. Only a superior Network can defeat an enemy Network. They both see Fortnite and Roblox as their real enemies, so their alliance allows them to join forces on a long-term plan to defeat those threats by first consuming and assimilating their own also-rans. This is going to be far easier to do on the Tabletop end, and not just with Official DND, as it will be in Vidya but it can be, and will be, done.
Blizzard has AI expertise. WOW is making AI DMs and players. You better believe that Blizzard's expertise will be applied to WOTC's aims.
You Tabletop and Vidya people gainsaying me now are going to be apologizing to me before this is over.
