I have an ElDorado .. single player version of Target Alpha .
I wish Gottlieb had made Target Alpha as a single player cause I would prefer the Sci Fi theme to Western .

Single player EM's are the best IMO .. because with multiplayers the game can't carry over from ball to ball .
The only Multiplayer EM I have found where this doesn't matter is Williams Lady Luck (which i also have) because with each ball you are playing to beat the dealer.
