Curtains drawn, drink in cup and in stomach, dinner enough for two, eaten by one, with leftovers for tomorrow, a couple of friends at text's distance if I'm feeling talkative, room aglow with a soft warm light from my lamp (not the blinding white light), and wall behind me lit from the glow of either my computer or the tv or both, unless I'm reading.
I don't like multiplayer if the person isn't next to me or I don't actually know them, and even then, there are few games where I actually want to play with other people.
When I go out, I'm out. I can be fun, and sociable, and have a decent rapport with the people around me.
But when I'm in, playing games, or reading, I'm usually by myself, and I like it that way. On occasion, I've played a co-op game with a partner, or some friends might come over and we'll all pass around controllers or beat on plastic instruments, but the majority of my gaming is done with just me.
And that's how I like it.
