Living in Pattaya in 30's as an expat

You can forget about the idea:  "I'll probably set up a board game cafe-style business for people to come to drink and play games," if you're thinking about opening the place in your name. That kind of place will most likely be included in the category prohibited for foreigners.

Are you able to direct me to any information about this law please?

You will not be allowed to do "any work" in the bar, you'll need Thai employees. It's more money involved in opening a bar in Thailand than you think. That means a lot of money to lose if it goes sideways.  It happens all the time. At the moment with so few tourists in Pattaya because of the pandemic, opening a bar as a foreigner isn't a very good idea. It "might" be better having a trustworthy gf/wife/business partner (if you can find one of those) that has a bar license and the rest of the papers needed.
