We used a tall IKEA type books case which had height adjustable shelves to store game boxes vertically, just like books. During a period when games were an entertainment focus, we used the gameboards as 'art' on the wall in the family rm by hot gluing a lightweight 'O' device on the backside.
We bought most boxed games at yard sales cheap, cheap, cheap as DKs get bored when they've mastered the concept.
