King Nothing is nothing more then a build and destroy scenario, but the author pulled it off nicely.
The playability was average. It was a build and destroy scenario with no triggers, nothing else much to say. The balance was pretty good. You had an ally and had to destroy all of the enemies. Creative? Well, nothin' special... but nothing bad, either. I was debating on whether to give the map design a 4 or a 5. The cities were excellently designed, but some of the terrain was a bit bland. Not too much to touch up on, but more natural patterns of terrain could be used rarely. The story... well there was no story. But there were instructions. The hints section gave you a few tips, as well.
If you're looking for a farely long and pretty good B&D scenario, I suggest you download Aceallic's King Nothing.
