An abundance of advertising, a few visual issues, some overly restrictive design decisions, weak new modes, and a major upping of the difficulty level might seem like a lot of potential hindrances for a game to overcome, and yet none of these problems are big enough to rob Guitar Hero III of the same brand of addictive fun that made the previous entries in the franchise so engaging. Certainly the fantastic track list goes a long way toward that end, but the gameplay is really what sells it. Sure, the difficulty can be vexing, but the game never loses that sense of "just one more song" addictiveness, even at the height of its challenge level. Once you start playing, you'll be hooked for hours at a time, both online and off. It might ultimately just be more Guitar Hero, but that's hardly a bad thing--in fact, it's a great thing.
