As you know from my previous post Fun post I really enjoy board games. In addition to sleeving my cards one of the things that really makes with some games even nicer is adding a foam core insert which can add these benefits:
Considerable faster game setup and teardown time.
Superior organization
Pride of making something special that makes your game
For simple games I enjoy making these with my spouse. However if the insert if for a super big and complex game like Gloomhaven I would rather spend the money on a pre-made insert
