Quoted from ForceFlow:Reusing existing parts and boardsets may help. So far, almost every newcomer has designed their own stuff from the ground up.
If I were building something new, I'd try to use as many off-the-shelf parts and parts designs as possible.
That would help keep R&D costs down, engineering costs down, tooling costs down, and production costs down. And also help get a game out the door faster. Maybe 1-2 years instead of 4.
Sure, every new game is going to have a selection of new parts in it, but didn't gottlieb and WMS have general policies/guidelines for their designers to use a certain percentage of parts that already existed in their catalog when designing a new game?
While I don't disagree with your statement generally, with the advances in electronics and other tech - it makes sense to re-visit old designs. One is often able to build better assemblies exhibiting better service up times and/or reduced costs.
