The second floor is where the video arcade games are, and there are many dozens. Some are actual arcade games such as Pac Man and Altered Beast. Others are home video games that in real life never were in coin-operated machines, such as Sonic and Mega Man. A few such as Sailor Moon R I'd never heard of a video game adaptation of. One, Sim-City, seems an odd fit as it's a strategy game and not an action one. But one can make a quick town with it (not sure how one can save their progress here).
