I don't mean to brag or anything, but I beat the game in 10 minutes. There was a bug in mine where it kept saying "out of fuel...$30,000...out of fuel...$30,000...out of fuel" ten times in a row, multiplying my earnings every time. I ended up with $3,400,000 by the end.
finally got all badges, it only took me 130 in-game days. It's really stupid when I have to serve Sargefan 62 times but Gino Romano only comes in 17 times. Also, fyi, don't worry about people who already have a gold star, just serve them empty pizzas. They're not worth your time.
made it to 12x, wow is my heart beating fast. really got crazy after a while, coffee breaks really helped keep me this long, but that's all I can stand.
