The bottom line is that Legend of Solgard is free and the mechanics and polish are all top-notch, and the game loop quite compelling, so there’s no reason not to give it a shot yourself and see which side of the fence you end up on.
Perhaps the highest compliment that could be paid to Legend of Solgard is that it’s not what you assume it might be just from hearing the genre in which you’d place it. It’s got something to offer all kinds of mobile gamers, from the very casual to the much more serious, and should expand the definition of a King title beyond what we’ve all known it to be for years now.
