Rise of Legends's units are impressive based on what we have played in the preview build, from the typical infantry units to massive battle units such as the Vinci's units who have things like a 19th century version of a battle mech to the Alim's fire birds. You also have special hero units for each side that add special bonuses. The research tree is there as well but this time Big Huge Games is making players make some choices as not all your upgrades will be available. Finally there are the special Dominance powers that the player can access if they achieve certain goals. For example, the military dominance power kicks in to the player who first gets four footsoldiers which then allows them to actually add enemies footsoldiers to your side.
