Diablo
1996 · Action RPG · PC
Overview
Diablo combined dungeon-crawling RPG structure with real-time action combat and procedurally generated levels. Players clicked to attack, clicked to move, and clicked to collect the randomised loot that enemies dropped — a game loop of kill, collect, and grow stronger that players sustained for hundreds of hours. Battle.net online play made the loot economy a community phenomenon.
Deep Dive
Diablo was developed by Condor Inc., which Blizzard acquired and renamed Blizzard North during development. The game's original design was turn-based; Blizzard shifted it to real-time action after playtesting. The loot randomisation system — items with random properties within defined parameter ranges — created the engagement loop that Diablo became known for. The game introduced the Tristram OST composed by Matt Uelmen, widely considered one of the finest game soundtracks of its era.
Developer Story
Diablo was developed by Condor Inc. in San Mateo, California, which Blizzard acquired partway through development and renamed Blizzard North. The game launched in December 1996 and sold over 2.5 million copies, establishing the action RPG subgenre.
Did You Know?
- Diablo was originally designed as a turn-based game — the real-time action system was adopted after Blizzard playtested the turn-based version and found the real-time alternative more engaging.
- The 'Cow Level' — a frequently requested secret level that Blizzard denied existed — was added as a real location in Diablo II as a response to persistent player requests.
- The Tristram theme — Diablo's ambient guitar piece — became one of the most recognised pieces of game music in the 1990s.
- Diablo's single-player mode was largely an afterthought — the game was designed primarily for the Battle.net online experience.
