I'm not sure if realtime games already get deleted sooner than the 30 days for longterm games, but I think that it should be less than it currently is. Definitely seems like it should be less than 24 hours before they time-out. Maybe someplace between 2 and 12 hours?

Maybe even a setting to control that yourself? I would personally set mine to time-out after 1 hour if I had the choice...

+1 for sure.

Somewhere between 1 and 2 hours, I would say.

Sounds very sensible.
