When World of Warcraft entered playtesting, Blizzard's quest design team believed they understood what players wanted. They were catastrophically wrong.
The game's early quest philosophy was borrowed directly from EverQuest, the industry's dominant MMO at the time. According to quest designer Jeff Kaplan, the goal was to mirror EverQuest's approach as closely as possible. Quests were designed simply to point players toward a group of enemies they could kill repeatedly to level up, just like in EverQuest.
The logic was straightforward: why reinvent the wheel? EverQuest worked. Players understood it. Blizzard would guess at the number of quests EverQuest contained, build a comparable amount, and launch with a familiar experience.
Then the playtesting began.
When Kaplan and his fellow quest designer Pat Nagle put the alpha build in front of internal testers, developers began storming their office complaining something was broken. Once players finished a quest, nothing happened. When asked why they didn't simply go kill the gnolls instead, testers responded, 'I'm not doing that, that's so boring. That's why I don't play these games. I need more quests.'
The problem was that Blizzard's testers were not MMO veterans. They had no context for EverQuest's design philosophy. They had no tolerance for aimless grinding. When Blizzard tested the game with developers who hadn't touched an MMO before, Kaplan and the team quickly realised their approach to quests wasn't universal.
The playtesting crisis forced a reckoning. Quest chains emerged as the solution; never-ending sequences of missions that would guide players from location to location, giving them a continuous stream of incentives to grind and level up. By peppering the game with tasks, even mundane ones, Blizzard was able to hook players who had hated grinding in previous MMOs.
During early playtesting, things went smoothly until playtesters ran out of quests, at which point they reported the game felt broken. For Blizzard's leadership, the answer was simply to add more. This was easier said than done; the studio ended up creating ten times the number of quests they had originally planned, resulting in WoW launching with roughly 300 quests instead of the 30 they initially estimated.
Today World of Warcraft contains more than 34,000 quests. What began as a crisis of vision during playtesting became the MMO's defining feature and competitive advantage. Blizzard's willingness to abandon their initial design philosophy, driven by feedback from players unfamiliar with the genre's conventions, created something genuinely new. The quest-driven narrative structure that emerged would become the industry standard.
Kaplan later reflected on the moment the team realised what had happened: 'We realized at that moment, that was defining in WoW's questing history. There's a new paradigm here. What previous games have done is not going to be accessible if we want to broaden our reach.'
