Well as a young adult, i can say still play with lego, not the way i used to on my childhood, in the matters you could relate things, events and characters with really no connection at all and a complete lack of logic, so i think as growing i cant do that anymore, focusing instead in developing scenarios, stories, and reasonable plots for the things that attracts me.
Or even give another use for the minifigs outside the MOCs, like on boardgames, a somekind of warhammer and stuff like that.
