In a recent announcement, Blizzard explained more Diablo III‘s online features. In particular, the game will allow for Global Play, meaning players from all regions – the Americas, Europe, and Asia – will be able to play with each other. However, servers are divided by region, and all characters, items, and friends lists will be exclusive to each one, meaning players will have different sets of each depending on the region they join.
This also applies to in-game auction houses, which are restricted to their ‘home’ region. And speaking of which, Blizzard has updated the game’s official site with a guide to the auction house. The guide details how one goes about buying or selling things, and clarifies transaction fees; check out the full thing here.
