Today Blizzard released the first expansion to Diablo 3, titled Reaper of Souls. The expansion continues the story with Act 5, which includes trips to Westmarch and Pandemonium. The level cap goes up to 70, there's a new class: the Crusader, and a new crafting NPC: the Mystic. The Mystic lets players reroll specific stats on their gear and change how the gear looks. The loot system has seen a drastic revamp, and Blizzard recently shut down the game's controversial auction house so they could have players find better and more interesting gear by fighting monsters. There's a new type of gameplay called Adventure Mode, which unlocks all waypoints and lets players go wherever they want, unrestricted by the campaign progression. This includes completely randomized dungeons, which can pull art and monsters from almost anywhere in the game. They've combined Adventure Mode with the Bounty system, which opens up randomized objectives scattered throughout the world. Blizzard has confirmed that the first major content patch after the expansion will bring ladders and leaderboards.
