There are two DLC that expand the race and class selection.

While many of the races don't return, a new class system adds a lot more variety to the returning races, and the base lineup of each faction has also been diversified more. Units are also more explicitly categorized as Infanty, Archers, Cavalry, etc, with each group having innate abilities and weaknesses (Cavalry is weak to pikemen but can Charge, Infantry can climb walls, etc). New to the series, units in combat are vulnerable to flank attacks weaker units earn their place on the battlefield by being distractions, setting up attacks to be delivered by your bruisers. Wizards (or rather 'Leaders') are back to being frontline units (casting from outside the battle costs twice as much), but are much safer from sudden death and empire failure. The gameplay of AoW3 mixes many aspects of the prior installments. Really, it was inevitable considering the type of game this is.

Set many years after the events of Shadow Magic, the world is going haywire again as the traditional, tree-hugging Elven Court and industrious Commonwealth head to war. The third official installment of the Age of Wonders series, Age of Wonders 3 is a turn-based strategy game released by Triumph Studios on March 31, 2014. Merlin, the trailer of Age of Wonders 3.
