Would go 2 wedgies, 2 two-player, two wms ems, and two EM games (gun, otherwise).
Atlantis (fun when set up right)
Spin-A-Card (fun period, kids love this game)
Super Spin (lots of gadgets to shoot at)
Snow Derby (spinners and chicks on sleds)
4 Roses (Not a great game, but classic and BG is wonderful)
Hot Line (Fun fishing themed game, and is hard)
Gun Games... Go to the PHoF as he has a rifle games on the floor to consider.
and if you must have just 8 wedgies as you originally mentioned...
1. Central Park
2. Atlantis
3. World Fair (great looking game)
4. North Star (great looking game)
5. Abra Ca Dabra
6. Subway
7. Jacks Open
8. Sing Along
and as options in case above are hard to find where you are at...
9. Buccaneer
10. King of Diamonds.
Good luck finding them all in original mint!
