When I first started making board games,
I'm always worried,
How can I find a factory to make my game,
If their product is poorly done,
Made not as designed,
or the product is not up to my client's standards,
All my hard work may be in vain.
These are the thoughts of a novice when making a board game for the first time.
However, when you have made a certain number of board games accessories and have a certain amount of experience, you will find that all these problems can be avoided.
This is the most important if you can't communicate with the factory. Then you will not be able to accurately communicate your ideas and designs to the factory for production. At the same time, you need to confirm whether the factory fully understands your true thoughts.
When it comes to price, it's not just the cheapest option. If their quote is higher than what I would like, do they suggest small changes in material, size, or quantity to help lower the price? Overall price compared to other manufacturers, are they competitive (not necessarily the cheapest)?
It's difficult to gauge the quality of what a factory can produce, and of course you can get some sample packs from them, but these aren't really representative of the final product offered in the store. I think your best bet is to ask what board game types the factory make and go to the store and buy one. Through the game in your hands, you can understand the production level of the factory.
