My favourite game of this genre

User Rating: 9.3 | Warlords Battlecry III PC
It's just a fantastic game that has both RTS and RPG flavor.
You have a selection of 16 different races to lead. And then
there are many classes that you can choose from.
Each race and class has their advantages and disadvantages.
Your attributes depend on both class and race.The campaign
is big enough to play for a long time. The campaign depends
on your Race, like undead and knight is always enemy. You
have to travel through the map many times but it never gets boring.
Main missions are really wonderful. The skirmish battle is another
thing that I like most beside the campaign.
