Gottlieb's Pinball Hall of Fame for PSP (PSN)

I'm totally enjoying the Pinball Hall of Fame on my PSP Go.  You get to pick from a few of Gottlieb's most popular tables, and naturally you have to beat a challenge on the simple ones, to unlock the others.  But also each table comes with a snippet of the history of the machine.  My favorites so far are the Genie machine and the Black Hole machine ... but I keep trying my hand on the love tester (yep, the thing that tells you how hot a lover you are) just 'cause it's, well, weird to include a machine that you can't "win" on a gaming platform.  Well done!
