The End User License Agreement - or EULA - is a legally binding contract between the developer or publisher of a software program (or application) and the purchaser of that software. However, unlike the purchase of goods or services, the EULA is, as its name implies, a license agreement. In other words, the purchaser does not own the software, they merely have a right to use it in accordance with the licence agreement.
"That means we do not own the Everquest game, we lease it"
