As an old man of 34 now, I am just getting back into the hobby of my youth. I grew up playing with Futuron, original Castle(Forestmen, Black Falcons, etc..), and Pirates. I love all of those themes to this day.
My kids just started really getting into Lego now at 4 and 6, and when I bought them some of the Star Wars sets for Christmas last year I got back into playing around with them too.
So far, I am spending most of my time in the Castle/Fantasy genre, but would like to dive into some hardsuits and mecha soon.
Since I am in balmy Michigan, this winter should give me ample time to be inside doing just that!
