We all have games we love, games we would never let leave our collection. I see trades on for sale threads, but all are permanent. What about a short term swap? Games of equal value for 3 months/ 6 months, etc. Maintenance is on the holder, similar to if you own the game. Just an example
Guardians of galaxy pro for a Deadpool pro.
Or
Bride of pinbot for junkyard
Or
Theater of magic for insert game here.
