Game suggestion needed

[Kevin Mullins]

Ok... here's the deal....
I had picked up a converted cocktail table game for my daughter's room.
Nice little cab that has Pengo in it.
Had thought that would be a cute game for a teen girl who always has friends over and such.
Turns out that it's a flippin' hard game!! (even set dips to easy)
So it has lost it's interest already.

Question is.... this is already set-up for Sega - Pengo.
It has a single joystick (4 or 8 way) and single button per player.
Without totally re-wiring it for jamma or something else, is there any older compatible Sega games that you guys would suggest? (plug-n-play)
(teen girls in mind of course)
