Well, I just found one of those. This one's called Pug Wars, and it's about as stupid as they come. You are an ugly little dog traveling around ten different locations in a city. You're also a pusher of doggie-toys (pug wars = drug wars, get it?). The object is to, in 30 days, pay off your money-man and make a ton of money buying low and selling high. Along the way, you have to deal with dog-catchers and you get to kick the asses of some french-poodles.
There's no graphics --just a grid of dog-products/prices and the occasional message-box informing you that the dog-catcher is on your tail. In fact, this game would do very well in text-mode.
Anyway, it's free and it's worth it for a half-hour of brainless fun, so give it a try.
