Hi, glad you like my stuff!
I don’t have any tutorials for making your own games or anything, but there are plenty of board game design communities on the web. For instance, the Button Shy discord server has lots of people talking about making games with regular competitions and discussions. There’s the /r/tabletopgamedesign/ subreddit. There’s a popular “Board Game Design Lab” podcast that interviews designers. And there are many more out there.
Just jump in!
