In many respects, Sword and Soldiers is an excellent game. You can criticise its blatant lack of originality and repetitive nature, but that doesn't stop it being a great deal of fun, while its wacky world will seduce many.
Ultimately it's about dispatching units as fast as you can and a mass of units pretty much always results in a win. I have to say that the AI is good and makes the battles fairly even and makes a win possible.
Sword and Soldiers is a great example of what a casual strategy game can do. It's deep enough for core gamers to enjoy, yet is simple enough that casual gamers can get in to it, while appreciating its deeper elements.
