CTRacer was a casual 3D MMO racing game in which players could build and customize their cars and compete against others for glory and advancement. The game featured various tracks to choose from, including several modeled after real Korean cities. The urban setting allowed for many quests that tested driving and other skills to earn bonus unlocks and points for upgrades. Several battle systems existed for competition on different scales, and guilds could form with custom logos. Attention was paid to make the cars handle as realistically as possible, and customizing a car didn’t stop at creation. There was a tuning system that allowed for tweaks to be made all along.
