I figured out my Arcade Paradise problem. Turns out I had to put the money in a safe before I could spend it. There actually was a tutorial for that; I just completely forgot about it.
One thing that bugs me about this game is that all the washers and dryers use a font that's supposed to look like those old-school digital numbers that are made up of a bunch of lines that get turned on and off to represent the numbers, BUT the font is not fixed-width. So whenever there's a number that contains a 1, the positions of the other numbers change in a totally unrealistic way. My immersion is brokeN!
Not sure how I'm feeling about the game otherwise. I guess I'm moderately enjoying it, but... I dunno, I was hoping for a bit more management sim and less laundry. I know I probably will get to a point where the arcade stuff is making enough money that I can just ignore the laundry, but if there's a basket of laundry sitting there, I'm going to feel obligated to wash it... and then I'm committed to 3 minutes of waiting for the washer and then another 3 minutes of waiting for the dryer. Also, a minute of real time equals roughly an hour of in-game time, so each load of laundry takes about 6 hours, and I need to leave by around 11pm, which means I can't start any laundry after 5pm, even though the laundromat is open until 8 or 9 (at least, according to the times on the door -- but that also says it's closed on Sunday, which isn't actually true).
I dunno, man.
In other news, I have a job interview on Monday and another on Tuesday, both of which I'm pretty nervous about, for different reasons.
