Quoted from mbaumle:Of the more modern era of EMs, I'd think maybe Fireball or any other multiball EM would be a good contender.
But lately, I've really been digging older woodrails. They really experimented with their designs, and gobble holes can be a lucrative hoot. Check out some of Harry William's designs back then. He was designing in ramps before it was cool.
I’ve shopped/restored Fireball, 4M BC, and Nip it, the only complexity really is the multiball circuit, had the most issues with Nip it, as it’s multiball circuit is counter intuitive and a PITA to get it dialed in... I’ve also restored an EM Cleo... could they cram more crap under the PF? How about WMS Solids N Stripes with the big ass split bank under the PF that keeps track of player 1 and Player 2 ball numbers pocketed...very cool feature!
