A week ago, Blizzard introduced a new program that restricted new players who had just bought the download version of Diablo 3 from accessing the full game for up to 72 hours.
Their fans were none too happy with this move (as our article at the time showcased.) Today, Blizzard has announced that program has been repealed in the latest patch, Patch 1.0.3a.
Due to security reasons, there will still be some restrictions on new accounts until purchases are verified. However, those restrictions will likely only prevent players from playing outside their server, and using the Real-Money Auction House. Blizzard has said the restrictions are often lifted within a day, but could still take up to 72 hours.
