Those are great games! I was at a GW in Mesa a couple weeks ago and saw a woman with a Mystery Date game in her cart. I was so tempted to hit her over the head, hide her behind the forest of halogen floor lamps, and make off with it. Alas, I was able suppress my inner Mystery Date thief.
I loved Underdog as a kid and wore an Underdog pin on my jean jacket all through my college years. That pin turned out to be a total guy-magnate and got me much male attention at bars and parties. There's something about Underdog, ladies. Of course, these days, I'd probably have to wear the entire game on my jacket to get any attention!
