One of the most satisfying ways to enhance a game I've found recently is to upgrade the insert. Some games have a ton of bits, and helping organize that can speed up setup, takedown, and even gameplay. Plus, I'm not a bit plastic bag fan. Judging by the multiple posts I've seen by people building inserts, I'm on the only one who thinks this way.
So, I'd like to compile a list of resources I've found for making/buying your own custom inserts, as well as share some of the one's I've (poorly, I'm new) built and some I recently purchased from Deadalus. Buying premade is not cheap, sometimes costing as much as the base game, but I've been very happy with what I've received.
