- Aside from the classic barbarian and sorceress, new classes have been created (Witch Doctor, Demon Hunter, Monk) all of which support both genders.
- Old areas have been revamped (think Tristram) and new ones are now available, including Caldeum, the great trade city.

However, this could be disputed after release, since attributes are no longer player controlled and so, for example, two level 10 barbarians will have the exact same stats, meaning that runes and equipment play a bigger role in enhancing stats, while skills focus on how those stats are used. This implies that the choice of equipment may have to reflect the choice of skills and this would only be countered if a large choice of equally powerful equipment is available, rather than one or two items.
