I always turned them off, unless I was just going to eat dinner and couldn’t save. The lasers for old systems like the PS2 and Sega Saturn have a longevity, and will wear out over time. I’d rather not speed that up since I plan on keeping them around. I was also scolded for wasting electricity growing up, so that is burned into my habits as well.
We have a big maple in our yard and more through the neighborhood. The sound of wind running through their leaves is very calming.
