Lego, custom minifigures, Harry Potter themed minifigs, Marvel movies (Loki, Captain America, Black Widow), writing, reading, fanfiction, science fiction books...
I've never been a Lego purist. When I was a kid my Lego bricks partied with the other toys. That means that Breyer horses, action figures, Lego, erector sets, plastic zoo animals, home-made shoebox houses, and dollhouse miniatures all hung out together.
As an adult, I play pretty much the same way. As long as everybody is having fun, it's all good.
