Quoted from TomDK:Thats the point ... it will not prevent bad quality but will be good for your game.
in my gameroom/garage is airconditioning and heating.
On the other hand I have pins for over 10 years (BC, WhiWi) and stored them the first years in a unheated garage ... no inserts are damaged and no DMD broken ... seems also a point of quality, coat, drying time, etc, pp ...
I think climate control is good, but ... Before I converted to all LEDs, those incandescent bulbs would put out so much heat I recall the backglass being hot to the touch, hot spots on the playfield, etc. Going through those warm up / cool down cycles every day (on location) I would think would be more stressful than any 'reasonable' environmental variables. Again, though, I do the same in my game room/garage and think it's a good idea, the games though should be able to handle the environment within their specs ...
