Guitar Hero
By BrendanI'd rather be playing DDR.
This may be an unfair comparison, but the fact is that Guitar Hero uses a very unique input device, much like DDR, so the two are inevitably going to go head to head. And the gameplay is very similar - match the strums (or your steps) to the beat. Though, in this match up, I'd put my money on DDR.
Guitar Hero suffers first from a polarization of the experience of its user base. Most people have almost no real guitar playing experience. When I watch them try to play Guitar Hero on the medium difficulty they get frustrated and upset very quickly, even if they are familiar with the gameplay concept from something like DDR. I've seen it take hours to pass a single song. However, when experienced guitarists have a go, they have no issue, and fly through the game. When I spent my three hours sitting down and beating the game, I only had to try two of the thirty songs twice - the other 28 I passed on my first try. Could an experienced dancer say the same after their first time through DDR?
So, what did the developers do to give someone like me more to do? They added a vast array of unlockable guitars, songs, characters, paint jobs...that affect absolutely nothing. I used the money to upgrade my guitar, and get a more stylish paint job, figuring that it would make me more popular and help me get a higher score on the songs, but it didn't. Other than your own skill, nothing affects performance in the game. The "cool RPG like elements" that make games like GTA so replayable are merely illusions here. So, now I've spent three hours beating the game, discovered that the unlockables are only aesthetic, and I've spent $60 of real money. Was it worth it?
No. Games shouldn't be dependent on higher difficulties or meaningless unlockable items to keep me coming back. In fact, after beating this game, I really have no desire to play it again. Being a hardcore gamer, most of the time I want to explore every inch of a game and unlock everything and complete it until I have dominated it 100%. But I don't want to do that with Guitar Hero. Maybe there are some people out there that will find the gameplay fun, rather than repetitive, boring, or frustrating, but I'm not one of them. DDR keeps me coming back with good solid gameplay that has no endgame (and the potential for burning calories), rather than dangling a double-fretted Gibson in my face.
