You can't sit at the Nintendo buying and selling stocks all day, though. You need to get outside, go to the gym, and take your bitch girlfriend shopping. But don't get up. You can do all of that without leaving Wall Street Kid. You'll never have to leave the house again since every boring detail of your real life is simulated in the game.
Time passes just like it does in the real world, only a little bit faster.
If you try to go to the gym, it'll be closed, and Prisila will give you shittier excuses to get out of spending time with you than Clark Kent gives Lois before he ducks out to become Superman. So 8 hours of every day, you get to watch your clock tick. And if mindlessly doing nothing isn't fun enough, you can always hit pause to extend the dead time to as long as it takes for you to start loving it. According to about three hundred obnoxious emails, you can click on the clock next to the box you use to communicate with your girlfriend to skip to the next day. That means that Wall Street Kid only wastes time at approximately the same rate as other bad Nintendo games.
