Way back in 2014, Blizzard Entertainment introduced the idea of Adventures to Hearthstone, a single-player mode where players would find themselves up against AI-controlled opponents who fit a specific theme. The first Adventure was Curse of Naxxramas, taking players to World of Warcraft's Naxxramas raid. The format continued until last year, with the release of One Night in Karazhan in August 2016.
Don't expect to see another one.
In a lengthy interview with Metabomb, Hearthstone art director Ben Thompson says the Adventures model is going away. Instead, mission content will be added directly to the expansions.
"At this point we feel it's best to continue to add mission content to the actual release set for several reasons," said Thompson. "With Adventures, we were somewhat fettered by the fact there were cards we needed to get out there, we wanted to add those 30-plus cards to the meta, but we couldn't gate those from players based on experience. If they didn't complete the Adventure and they don't get those cards, that sucks."
In order to make sure players got access to those cards, Blizzard had to make Adventures less complex, meaning veteran players weren't enjoying them as much. Essentially, the model wasn't working for Hearthstone's core players.
"This is a way we get to put the challenge into them - and certainly with the Dungeon Run there'll be a ton of challenge in there - but there's no gated content behind that, other than a card back for beating all nine heroes. It's very different from "I don't have a card I can add to my deck now and make a certain deck type," said Thompson.
Missions akin to Adventures will simply be folded into the expansion content. With the effort of creating Adventures going away, Blizzard can put that time towards creating full expansions for the game. In fact, Thompson said the team is looking to add three full expansions to Hearthstone in 2018.
"For that reason, putting together three full releases with mission content is a big part of how we see the game going forwards," said Thompson. "It's hard to put definitive numbers to those sets, but three full sets - whatever that may mean, give or take cards - is absolutely the plan, with missions in each."
The full interview is much longer and well worth the read if you're a Hearthstone fan.
