Quoted from dnaman:
Pinball Brothers only have two active pins. Alien was a serious make or break, recovery attempt, which appearently they met and have exceeded expectations on. It is their flagship product and still has plenty of 'money on the table'. This is not the case with HW. That said, I am still hopeful.
Yea that's the worry, Alien is still a machine in production for however long they can sell it. Halloween/UM were one and done games that sold out, so the pressure is not the same, but we have to hope that reputation to provide a quality product remains on the fore front.
