I'm a person who is the majority of the time hosting guests, partying/chilling with friends, and I love my private/gaming time.
My favourite environment is, again, to be alone. I only seem to play games late at night, into the early hours of morning. I love the rain.. love it. (not only is it atmospheric, but makes me feel less bad about not being out, doing, stuff... works all round)
I like a warm soft light, warm, or cold with a blanket, & depending on situation either a steady supply of beer & fruit, or tea/hot chocolate.
That's my ideal time
