I think the have release to many GH games, in the last year we have had, GH3, Rockband, GH:Aero, GH:WT, GH on tours, GH on tour decades, and Rock Band 2... You go into game stores and the place is cluttered with Different SKUs of all the different games and systems they are for.

Oh yeah. I touted that in my review. I am going to import all the songs and sell the game and the wired controllers. It makes the game even more cooler than GH.

@ Big Jon - yeah, son, you can't swing a dead cat without hitting a GH sku. It still seals, but they need to scale back big time. The money will be there.

Lol. Wii Music is so awesome, PS3/360/PS2 owners won't buy Guitar Hero.

not for the wii

Ok, maybe I'll give a fuller anbswer, because I'm getting a few weird looks.

The 'music' genre of games doesn't seem to have peaked, but individual release may see lower sales.

Guitar hero games are coming faster between releases
Last generation there was very little overlap between the games, Guitar Hero, Singstar, Donkey konga all lived seperate lives.

Now we have GH, RB, Wii Music, Singstar, Lips all having some crosssover, and all with games released in the last month or so. Of course they are going to cannibalise each other.
It doesn't seem like Lips will warrant a sequel (imo) and if Wii Music does get a sequel, it wont be a 'one a year' affair like GH and RB, so next year is looking up for GH, RB and Singstar.

The existance of downloadable content also extends the lifespan of these games (making decreasing sales not surprising) and means the devs get more money per game (making the news not worrying)

PS Wii Music will be huge :P

Maybe

The Guitar Hero series will soon be surpassed by the impending Keytar Hero. Keytar Hero will revolutionize the music simulation genre.

Depends if the songs get better or worse in the later ones...

If you have RB1/2 or GH:WT why would you ever buy another one?

For more songs? You can get new songs every week with DLC, plus you get to choose what they are.

For better/more instruments? People do not want two drum sets. What else can they reasonably add?

New feature? Nothing i can think of that people would want.

I think the weekly DLC devalues the newer games. If there were no DLC, people would be forced to buy the new version to get more songs.

That's just your opinion WiiStation360

I honestly don't see any differences between CoD1 and CoD5, but apparently some people do so they continue to make games. I'm sure GH will be the same
