Unlike the stations in other parts, the Akiba branch seems not too popular with the FGC, more popular with tourists for the cranes. Has a fighting game floor, with reportedly lots of smoke. Apparently at the cranes section it’s easier to win because they don’t reset the prizes so often. Also it’s reported that the men’s urinals will measure the velocity and volume of your pee… Could be fun!
