Halo 3

THE game that changed the face of the Xbox 360 and Microsoft. It has sold millions upon millions of copies around the world, and set a new bar for gaming. However, it has also caused (along with World of Warcraft) a dramatic spike in video game addiction. Countless players have been "pwning noobs" on Xbox Live for hours on end, but have ignored the needs of their parents/children/girlfriends/boyfriends/fiances/spouses/significant others. They have been more obsessed with hearing "killtacular!" than saying "what do you need, honey?" Its a tragedy of some sorts; it really is.
