I haven't made a productive post here in a bit so I thought I would share with you my stupid easy solution for modular game tables. The only materials you need for this project is cold hard cash, or credit, or debit, or checks I guess. That's because the perfect modular game table has already been made for you in the form of 2'x4' folding tables you can get from hardware or department stores.
We also have four 2.5'x5' tables so we can make a massive 5'x10' game table which we use for for our space port but it takes up most of the space in a two car garage and because the tables aren't the same brands we have to shim some of them up a bit to make them match.
As I said this isn't a very cheap solution but it's super easy to deal with and store away when we don't need them. We've tried other types of game table solutions but this is the one we favor because it's so easy to deal with.
