I've been playing around with a Kill-A-Watt electricity monitor for the last couple of weeks, measuring the watts for various games when in attract mode. I was surprised at the spread between the highest and the lowest. The best of the bunch? WrestleMania with Stern's new Spike system. Here are the games I tested, along with the wattages, highest to lowest:
Theatre of Magic - 223
Star Wars Episode I - 199
Monday Night Football - 198
Demolition Man - 185
Tri Zone - 133
Power Play - 125
Strikes and Spares - 119
Captain Fantastic - 93
Metallica (Pro) - 88
Medieval Madness (LEDs) - 84
The Walking Dead (Premium) - 82
Star Trek (Premium) - 77
Big Shot - 71
Spanish Eyes - 67
Nip-It - 61
WrestleMania (LE) - 50
