The appearance of the game world was praised by critics. Most popular was the fact that a player could run from one end of the continent to the other without having to pause at a "loading screen" while part of the game is retrieved from storage.[86] The environment was described as "breathtaking". Players found it difficult to become lost, and each area in the game world had a distinct look that blended from one to the next.[21] Critics described the environment as "a careful blend of cartoon, fantasy art, and realism".[81] The game was found to run smoothly on a range of computer systems,[10] although some described it as basic,[21] and mentioned that the bloom light rendering effect can blur things.[20] One reviewer described the ability to fly over long stretches of scenery as "very atmospheric".[83] The user interface was liked, being described as "simple", with tooltips helping to get the player started.[10]
