PvP combat
Player versus player combat (PvP) has not yet been implemented in Diablo 3 Gold, but has been announced. On March 9th 2011, Blizzard announced that PvP was delayed, and that they will enable it in a future patch. Lead designer Jay Wilson said in a post on Battle.net that the PvP Arena system will arrive in a post-release patch. “As we’re counting down the days until we’re ready to announce a release date for Diablo III, we’ve come to realize that the PvP game and systems aren’t yet living up to our standards,” he said. Blizzard said the PvP patch will add multiple Arena maps with themed locations and layouts, PvP-centric achievements, and a quick and easy matchmaking system.
Players will participate in PvP by choosing from their existing characters, with access to all of the gear and skill they have gathered from playing the game in single-player or cooperative mode. There will be both ranked and unranked gametypes. When participating in ranked games, players will earn points for advancement based on the number of kills, accomplished objectives, and victories they acquire throughout matches.
Auction house
On August 1, 2011, it was reported that Diablo III will feature two types of auction houses; one where players spend in-game gold and another where players can buy or sell virtual items for real-world money. The real-money auction house will not be available in Hardcore mode.In the gold-based auction house, a flat fee of 15 percent will be taken from the final sale price of an auction. The real-money auction house fees will be $1 USD, €1, £1, etc. from equipment (weapons and armor) and 15 percent from crafting materials. There is an additional 15 percent “cashing-out” fee from proceeds gained selling items in the real-money auction house.
Hardcore mode
Diablo III gives players the choice to make hardcore characters, similar to Diablo II. Players are required to first level up a regular character to level 10 before they have the option to create new Hardcore characters. Hardcore characters cannot be resurrected; instead they become permanently unplayable if they are killed. They also do not have access to the real-world money auction house. Hardcore mode is intended for experienced players who enjoy the additional thrill of having only a single virtual life. Hardcore characters are separately ranked, their names are highlighted with a different color and they can only form teams with other hardcore characters.
