Maybe break the list into:
- Companies SHIPPING
- Companies DEVELOPING
- Companies IDLE/INACTIVE
In my opinion, until someone can send you money and you can turn around and ship them a game, you are at best, developing your pinball game and pinball company.
There is a massive jump between "we built a couple games!" and actively shipping pinball.
- Dutch Pinball
- Chicago Gaming
- Heighway Pinball
There are a lot of us (FAST included) who would love to be on the SHIPPING list and are working hard to be there someday.
Kudos to those companies successfully shipping games, you are an inspiration to the rest of us!
