The game's auction house was pitched as a way for players to trade items in complete security. Soon that was just a bad memory, but another decision taken by Blizzard had a longer-term and arguably more damaging impact. The always-online requirement was unpopular even before it led to a painful launch, when log-in servers crumbled under the immense demand. Diablo 3 sold extremely well but left a sour taste for its community, and for once not just among the vocal minority. It has an audience to win back and a reputation to save. But it has bigger fish to fry than what's listed on the back of the box. Its headline additions are a new campaign act, a new character class, a raised level cap and a new gameplay mode. So Blizzard expansions are a big deal, and few have been more crucial than Reaper of Souls. In these expansions, the new ideas and hard graft that have been poured into the renewal, rebalancing and restructuring of the original game usually exceeds what goes into your average blockbuster sequel. In an age of bite-sized downloadable add-ons, their premium price tags raise eyebrows, even with the generous supply of new content - but that content is usually less than half the story.

With the exception of Firaxis, there's no-one left that makes expansion packs like Blizzard.

The first expansion for the action role-player makes the changes players wanted - and a good few more besides.
