Pinball Magic, much to my disagreement, won this contest

IN reality it's Fireball, because it's worth so much and super hard.
Congo's is great fun but the fact you most likely get a few wacks at it makes it a little cheap
PM's is fun but easy...and starts MB too quick if it's lit
Quoted from pinballshark:El Dorado is deceptively hard.
Uff man those game like that and Target Alpha are so damn tough.
