Low Guitar Hero: World Tour Sales - Too Many Rhythm Games?

Rhythm Gaming is all the rage, or is it? Turns out Guitar Hero: World Tour didn't meet or exceed the figures they hit with Guitar Hero III. Where GH3 brought in $115 million in the first week, GHWT brought in $67 million in the same time frame.

Why?

There are plenty of factors that could cut down the sales units, considering those that can purchase Guitar Hero World Tour don't have to purchase additional instruments to play the game like they played GH3.

I'd say too expensive games...

I won't buy a game for so much money or for less money and not getting the whole experience.

"Rock Band 2: This game arrived before Guitar Hero 3 and folks went for this game instead because it was first to launch. Some gamers have to make a choice on which to purchase because they can’t buy both."

Rock Band 2 Came Before Guitar Hero: World Tour (not 3). Just wanted to clear that up in case some people are wondering about the new game from each franchise.

On topic the only way I will get GH:WT is if I end up returning a christmas game which is unlikely seeing that im getting 5 of the biggest games this christmas, I might rent it and play it using my Rock Band/Les Paul stuff.
