The reason FM is a walk-on even on the busiest of days isn't because it's hard to find. Most ride it too cool off and take a break or soak up the nostalgia. But I doubt very many people are leaving the park bragging to there family/friends about there FM score or how much fun they had on it.
I think the guns and the noise that goes with them probably keeps more people off than it attracts.
I think those who think the video game generation(s) would be bored and not ride if they had to watch and listen and read instead of paying attention, are not giving nearly enough credit to kids and childhood imagination.
I think kids can still have fun without adults bombarding them with stimulation.
Yeah, I'm one of those guys. I think the buzzsaw was great. The rockslide was great. The gushing pipe was great before it was just a trickle. The silence and dark and chirping crickets were great. And I think all those things would still be great, but no one will even notice as long as it's a laser tag game instead of a dark ride.
