I've finally settled into a pattern. While I have lots of purchased and homemade terrain and game aids in the wings, the following see use in every game of my D&D campaign (I'm the DM).
1. My House
Best. Game. Aid. Ever. Players come to you can I have all my books and game aids on bookshelves behind me. I always have tables and comfortable chairs for the group. I have no issues with surrounding noise making it difficult for us to hear each other. I have a stocked fridge in arms reach. I can set up everything on the tables before going to bed and all I have to do in the morning before players arrive is start the coffee.
2. Decent chairs.
I would like to upgrade them, but they a better than wooden kitchen chairs and any chair I've every seen at any FLGS or gaming convention. I run eight-hour games. The cost of good office chairs may seem out of reach, but I got mine for a steal on Craigs List from a company that was downsizing. Another good option is to check out furniture rental companies. Many of them have furniture clearance warehouses where you can find good deals on quality used office furniture.
3. Digital battlemap.
I have a 40" display encased in a custom made case by
Collabrewate. I is so much easier to throw up a map on this than to have to print out battlemaps on large-scale printers or to have to pause the game to draw things out on a wet/dry erase grid mat/board.
4. 2D miniatures.
Someone above mentioned Arc Knight. I backed their Kickstarter and have hundreds of fantasy minis from them. I also have a Silhouette paper-cutting machine that I use to quickly and cleanly cutout 2D paper miniatures.
Printable Heroes and
One Monk Miniatures are my go-to creators. I also bought the cardboard 2D miniatures for
Tome of Beasts and the
Creature Codex by Kobold Press. I bought a large box of US letter-sized envelopes to organize the minis. I just put the flat minis into an envelope, write the name of the creature or NPC type on the envelope in large letters with a black marker, and then file them in a box that is letter-size width and organize them alphabetically. I have thousands of minis organized alphabetically at my fingertips. And I can easily grab the box and take to FLGS without having to do any preparation.
5. Slotted Bases + Alea Tools
All of the Arc knight and paper minis I have, have tabs at their bottom for use with slotted bases. I have a bunch from the Tome of Beasts, Creature Codex, and Arc Knight kickstarters. I also bought a bunch from
LITKO. I also bought a set of Alea Tools magnetic status markers and I put magnetic stickers on the bottom of my slotted paper bases.
6. Bag of Superior Sorting
I got this from a
kickstarter. The creator had some personal issues and delivered the kickstarter very late and it unfortunately looks like these are not in production. But this is the greatest dice bag I've ever owned.
7. Measuring Sticks
I made a number of measuring sticks using the instructions on the
DM's Craft You Tube Channel. I originally created these for gridless play as I was using felt terrain and gridless maps as well as homemade terrain. But even with gridded battlemaps, they are helpful to quickly measure movements without having to count squares.
8. Time Tracker
I printed out and laminated the
Time Tracker by Woopdedoo on DM's Guild. Tracking time is important in my current campaign and this makes is fairly easy.
9. Laptop and Software
While I could do much of my DM work on my smart phone with D&D Beyond, I need my laptop to run
RealmWorks, which I use to manage my campaign and display maps. Along with RealmWorks, I use
Hero Lab (for monster statblocks and combat tracking) and
Evernote (for taking notes).
