Strange EA is up there, unless growth in FIFA is really that good. They don't have much else going for them (or a booming mobile market, maybe?)
Activision is a touch more perplexing unless it's on the Blizzard side. Call of Duty is stagnant, World of Warcraft on a slow decline. Is Hearthstone really all that?
Monster Hunter: pissing me off since 2010.
