Guild Wars coined 'CORPG' in 2005. The MMO genre caught up

Key Takeaways

• ArenaNet branded Guild Wars as a 'CORPG' (cooperative online RPG) in 2005 to distinguish it from traditional MMOs
• The features ArenaNet used to differentiate Guild Wars, instanced content and NPC party members, are now standard in WoW and FF14
• Guild Wars 3 is in development, with ArenaNet reflecting on the original game's design philosophy

ArenaNet tried to escape the MMO label when it launched Guild Wars in 2005. The studio invented a new term, 'CORPG' (cooperative online RPG), to describe a game where players assembled small parties of heroes, henchmen, or friends to tackle instanced content. You only saw other players in social hubs. The branding failed completely. Players and press called it an MMO anyway, and ArenaNet eventually accepted defeat.

Here's the twist: those exact features ArenaNet pointed to as non-MMO traits are now everywhere in the genre.

What made Guild Wars different in 2005?

In a news post last week tied to the Guild Wars 3 announcement, ArenaNet got nostalgic about the original game's design. 'Guild Wars Reforged is, at its core, a game about a small team: a player and their assembled team of henchmen or hero NPCs or other players they want to bring along with them, overcoming challenges in a predominantly instanced game,' the studio wrote.

The key differentiator was isolation. Unless you invited someone, you never encountered other players outside hub areas. This was deliberate. ArenaNet wanted to avoid the grind, the monthly fee, and the downtime waiting for groups that defined MMOs like EverQuest and the newly launched World of Warcraft.

Players didn't care about the taxonomy. They saw an online RPG with thousands of concurrent users and called it an MMO. ArenaNet even won MMO-of-the-year awards. 'We gave up on the CORPG angle since it didn't stick with players,' the studio admitted, 'and we simply embraced what everyone told us: we'd shipped a unique kind of MMORPG.'

Why do modern MMOs look like 2005 Guild Wars?

Final Fantasy 14 and World of Warcraft now include NPC party systems. FF14's Trust system lets you run dungeons with AI companions. WoW added Follower Dungeons in 2024. Both games have shifted toward soloable content over the years.

PCGamer's Harvey Randall, who wrote the original piece, noted the irony: 'When you describe a game where you rarely interact with players outside of social hubs, you can describe a ton of modern MMOs depending on how strict you're being. Sure, I'll see players occasionally divebomb a mob in my periphery in WoW or join a mob of particle-effect flinging adventurers for a public event, but I'm not exactly talking to anybody.'

Raph Koster, who worked on Ultima Online and Star Wars Galaxies, has expressed concern about this shift. Open-world sandbox MMOs, the type Guild Wars explicitly positioned against, fell out of favor. Instanced theme parks with social hubs became the template.

What's happening with Guild Wars 3?

ArenaNet's news post wasn't just retrospective. The studio confirmed Guild Wars 3 is in development and discussed Guild Wars Reforged, which preserves the original game's core philosophy. The new game aims to address issues that pushed players away from Guild Wars 2, including PCGamer writer Lauren Morton.

The franchise launched in April 2005 with zero monthly fees, a radical choice when WoW charged $15 per month. Guild Wars sold over 5 million copies in its first year. Guild Wars 2, released in 2012, accumulated over 11 million registered accounts by 2017.

Twenty years later, the series continues. But the genre it tried to avoid has absorbed its innovations.
