I think it's a lame idea... I've posted this same post several times over the last 2 years, but I'll do it again...
We tried the whole guitar hero / and rock band thing... I did it with 2 12' screens, and a full JBL SRX system with 4 18" subs , 2 dual 15" tops, and about 16,000 watts of power as well as moving head lights, LED's, and all that... I mean big time....
It didn't fly worth a crap.. Girls were still coming up all night saying "this is so ****in' lame.... can you play some music we can dance to?""
Several reasons why it doesn't work......
The idea is about 1 1/2 years too late... everywhere here in Atlanta at least has already tried it, and summarily scrapped it. If you're just hearing about this now, sorry, but we were playing rock band in the bar christmas 07'... it's not that it's not a cool idea, it's just an old, outdated, and proven failure for bars...
It's too repetitive... the patrons there don't want to keep hearing the same song over and over...
For rock band, one lame ass ruins it for everyone else... so if everyone's not in sync, it sounds like ass...
Everyone owns a PS2 or XBOX... the bar will pay you for two weeks, when the initial gee whiz burns out (usually about 2-3 weeks), they'll then decide to save money, and they'll continue without you for another 2 or 3 weeks, until everyone in the bar finally complains enough that they drop it.
It doesn't involve enough people... interest is lost very quickly...
The people who are into the video games are usually either under age, or don't drink... the video game demographic is not known for being big spenders... (this information is based on years of having done madden tournaments, dance dance revolution, Guitar hero, Rock band, and others...)
I'm just saying, I have yet to see a single individual do well with this...
it definitely doesn't have the potential to take over karaoke, as I rarely see it last more than a few weeks..
people can stay home and listen to their kids or little brother play that all week... no one wants to hear that at the bar....
now it's a great add on for bar mitzvah, kids parties, and even corporate parties... but not as the main entertainment...
