ChangYou.com (US) Inc. is a subsidiary of ChangYou.com, Ltd. (NASDAQ: CYOU), a leading developer and operator of online games in China. Interpreted into English, "Chang You" means "Playing games brings happiness". Specializing in free-to-play (F2P) massively multi-player online role-playing games (MMORPGs), ChangYou.com (US) is a leader in the growing movement to bring F2P MMORPGs to the United States. The advantages of the F2P model are clear; our players are never required to pay for our games—there is no initial retail or ongoing subscription fee. Our business model is supported by micro-transactions available within the game for players who want to purchase fun, expressive masks and clothing or various item upgrades for their in-game characters. No one is ever required to make a purchase of any kind to enjoy and complete one of our exciting games. We have released two exciting F2P MMORPGs in the United States: Dragon Oath, Blade Wars, and plan to release another dazzling 3D MMORPG, Zentia, soon.
