It was, in fact, the title that made me truly care about online gaming, thanks to its fast-paced "meat grinder" style of play and fantastic promotion system. It was one of the biggest releases of its year, critically acclaimed and popular enough to knock Halo 3 from the top spot of Xbox Live's most played titles.
Infinity Ward had done an excellent job with a game that not only provided addictive multiplayer, but an engaging and sometimes shocking single player campaign that truly distinguished it from other war shooters. Imagine the dismay of gamers everywhere then, when it looked like Treyarch was going to play it safe and set the follow up title back in World War II".
