EA has implemented a new policy called the "Origin Great Game Guarantee", allowing users to return game they're not happy with for a full refund.
As detailed in an announcement post, the offer only applies in the first 24 hours after you first launch a game; within seven days of purchasing it; or within seven days of launch for pre-orders - whichever of these conditions applies first.
The full policy details are available for your viewing pleasure, but a few points are worth highlighting; this only applies to EA's games, not third-party titles, and to games purchased directly through Origin - if you purchase the game elsewhere but activate through Origin, you'll have to take it back to the original retailer to request a refund, which will depend on the business's policies.
EA won't make you jump through hoops, apparently; to request a refund, just find the game in your order history, click the appropriate link, and answer "a few quick questions". Reasons a gamer might want to return a game include not being "riveted by the storyline, or sucked in by the action" or incompatibility with hardware.
The refund policy went live today in 20 countries, and will roll out to other territories before the end of September, along with several other improvements to the Origin client. Origin recently expanded to Mac, too.
