that the game has sold 9.5 million copies worldwide. Reviewers praised the game for its impressive graphics, expansive game world, and schedule-driven NPCs. Eurogamer editor Kristan Reed stated that the game "successfully unites some of the best elements of RPG, adventure and action games and fuses them into a relentlessly immersive and intoxicating whole." GameSpot's Greg Kasavin wrote that compared to Morrowind, which was one of the best role-playing games he has seen in years, "Oblivion is hands-down better, so much so that even those who'd normally have no interest in a role-playing game should find it hard to resist getting swept up in this big, beautiful, meticulously crafted world." X-Plays Jason D'Aprile stated, "All the games in this series have been known for their sheer vastness and freedom of choice, but the Elder Scrolls IV takes that concept and runs with it." GamesTM editors noted that the game is "heavily steeped in RPG tradition, however, its appeal stretches far beyond the hardcore RPG demographic thanks to its ease of play, boundless ambition and focused attention to detail." Scott Tobias of The A.V. Club wrote that the game is "worth playing for the sense of discovery—each environment looks different from the last and requires a nuanced reaction—makes the action addictive." GameZone staff commented on how one can spend a lot of the gameplay time by leveling up his or her character, doing various quests, and customizing the character before even starting the main quest. IGN editor Charles Onyett praised the game's storytelling and "easy to navigate menus". Despite the praise, Patrick Joynt of 1UP.com criticized the conversations between in-game NPCs and the player: "When an NPC greets you with a custom piece of dialogue (such as a guard's warning) and then reverts to the standard options (like a guard's cheerful directions just after that warning) it's more jarring than the canned dialogue by itself." Game Revolution's Duke Ferris noted that "the voices occasionally repeat" but was impressed that the developers managed to fit a lot of voiced dialog into the game, where most is "high-quality work". GameSpy's Justin Speer criticized the "disruptive loading stutters while moving across the game world" and long loading times. Speer noted several miscellaneous bugs, such as unintended floating objects and unsynchronized lip-synching and speech. Onyett of IGN criticized the disjunction between enemies that scaled up according to the player's level and not their combat abilities
