Six games isn't too much space really. Guessing you already thought about repurposing rooms in your house? We rarely have guests, never use the dining room, and don't need extra bedrooms .. so those have all been turned into fun rooms. Don't see a lot of options besides storing in your house, storing out of your house, or selling them off and buying again down the road.

Maybe you can find trustworthy people locally to loan them to until this passes over. Hey, which games are they again?
