Stop me if you’ve done this before: you’re playing your favorite card (or otherwise rank-based game), hit up your standard few matches for rewards, keep your ranking stable, then log off. It’s a problem for both the publisher and the player, as the former wants to keep you logged in as long as possible, and the latter often just wants more stuff to do in a game they love to play.
Blizzard has been experimenting with these concepts in the past few years with mechanics like Diablo III‘s expanded adventure mode, Overwatch‘s arcade and now, an eight player wacky Auto Battler-inspired Hearthstone gametype. So far, it’s pretty promising.
