Original: With the release of The Sims 2 in 2004, Maxis' logo was only displayed at the back of the box as well as the title screen at the launch of the game.
Simplified: Products were shipped under the Maxis logo for several years until 2004, when The Sims 2 had only the Electronic Arts logo on the box cover. As of October 18 2006, with the release of The Sims 2: Pets expansion pack, the Maxis title has been removed from the game's start.
