I'm back! Quick question about room temperatures.

[Doomsayer]

If I remember right they have suggested around 21-23C. and so low levels of UV that are possible.

Edit::

From book museum they suggest around 18C, 50% humidity and low to none level of UV. So.. Maybe 18-20 for games and I won't suggest any humidity. But those are from museum conservation site. If you want more information from them, I can translate or you can find english site about this subject.
