it's a cool idea.
We have been trying from early on this year to increase the console presence at GLs.
Infact, the new HQ opened with 4 consoles and 4 TVs, joystick setups, the works.
We see about 10% console usage compared to much higher figures on the PCs.
The majority of the console gamers are kids from school. Other members only use 'em to pass time while waiting to get on a PC. lol
That's the reality.
I love the console gaming scene, especially the competitive fighting game scene but I'll be the first to confess that it hasn't been a big hit at a GL.
You're hardly offering anything there that a bunch of gamers can't get at a friends house for free.
Why pay?
We still get the crowd for a newly released game, but once that makes the rounds and everyone gets it at home. sweat buss.
They only return for challenges and competitions, which is cool, but not enough to run a business on imo.
There are other GLs like FoxintheBox that run only XBOX systems.
No PCs. Check 'em out.
Note, their strength is Halo not the fighting scene.
Fantasy V were also big on consoles (as was Max with arcade boxes and all). They've both since moved more heavily towards the PC scene so those aren't good examples anymore I guess.
I'll ask Foxinthebox what their experience has been thus far as a console only shop for those of you interested in doing the same.
