I'm beggin you, when you join a party, (in the menu screen) have the other player's party characters walk in from the sides of the screen, and do things like fluff up the pillows and sit on the couch, lean against the wall, pick up the M4 and start making sure it's working, etc.
This would be flippin awesome to see and be amazing as you would be able to see other people's outfits and accessories.
Each individual person in the party would be in the center of their own screen, on their own computer, and be surrounded by their party-mates. (So they can distinguish between themselves and others.)
Maybe have player nametags? I dunno.
I think it's cool.
