I think I tend to try to emulate my favorites when it comes to game design. What are your favorites and do you want to make similar games?
Just off hand my favorites are splendor, kingdomino, sushi go, king of Tokyo, New York slice, tsuro, forbidden island, fox in the Forrest, and xenon profiteer, and of course D&D
I like shorter games that are easy to introduce people to and hopefully foster good relationships within friend circles
