11. Guild Wars (PC)

Although strictly a PC-only title, Guild Wars was more influential in the past decade than just about any other PC MMO RPG. Why Guild Wars rather than World of Warcraft, which has many more subscribers?

One simple reason: Guild Wars put to death the concept of high monthly fees for MMOs. It was the first MMO to only charge for the software and make playing the game free of charge. It was as revolutionary as an acne solution that works!

Sure, Guild Wars has seen its popularity wane toward the end of the decade, and there are still some MMOs that charge monthly fees; but thanks to Guild Wars, they are no longer the only online game in town, and the recent wave of “browser-only” or “free download/free to play” MMO RPGs is due in large part to the ground broken first and more importantly by Guild Wars.
