I also come up with my first bit of strategy. I decide that I’ll get in line for the more popular machines and if one opens up around them that I haven’t played, I can quickly hop out of line, knock it off, and get back in. But when I leave the Doom machine line to play Star Trek: TNG, I find the Doom line has doubled by the time I’m able to get back to it.
Unfortunately, it doesn’t take long for the crowds to return and I’m still well below my mark. It becomes clear that my only shot at completing the challenge would have been to sneak in after hours, turn the power on and get out just before the police showed up.
