Kingdom Wars 2: Battles is set in a fantasy world where Orcs, Elves and Men have been at war for a very long time. This game takes place about 35 years after the first one, and the idea is that they have been fighting each other practically non-stop the entire time. The campaign opens by explaining that a human city is under siege by some of the last remaining orcs in the world, after the destruction of their hometown by the Elves.
There is a bit of history to the war, and while it may seem overwhelming at first, the game does a good job of summarizing what has come before. The campaign seems to involve a fair bit of switching around your races, with only the first level being made up of a human section followed by an Orc section. These are not optional, it's just how the game seems to prefer to A) teach you the basics and B) structure the story and show it from a different point of view.
The game seems very focused on multiplayer and community. Even in the main menu, there are plenty of options, and most people are heading for some sort of interaction with their fellow players. There's the option to settle rewards with each other, or join guilds and do all the other alliance-y things you can imagine, and there's a chat forum.
