Yes, I am a grown man with a master’s degree and a full-time job… and yes, I still play with Legos! As a solidly middle-class GM, without a lot of money to blow on gaming minis, paint supplies, etc. I often turn to creative, low-cost solutions when trying to represent things on my gaming table. (For those of you who are unfamiliar with D&D, the game does not come with game pieces)
One of my favorite techniques for whipping up custom characters, beasties and objects is to build them from Lego. I keep an assortment of Lego mini-figure parts in my DM toolkit so that I can put together characters on the fly. I also have a bin of bricks near the gaming table for creating other impromptu elements.
