The Campaign of Elinia is a campaign that is mostly for beginners, and it's very easy. It may seem a bit like the original SH campaign. There is a little eyecandy, not much, and mostly everything is easy. It's maybe a bit harder than the SH campaign at first, but the later maps will be harder. Enjoy, and please comment.
And one more thing:
In mission 6, where you are sieging the Rat's castle, you shouldn't have difficulty hard or very hard because if you do you won't have any siege weapons. (And of course all the maps doesn't play on the piece of ground on the minimap, it's just an example from mission 1.)
