Seats & Spaces
You'll need big and comfy and plentiful if you're going to be camped in the room for hours at a time with lots of friends. Remember to provide plenty of spots for people to sit and rest their feet as well as their food and drinks while they're playing or watching. If you don't have a huge amount of space we suggest getting a coffee table that can easily roll out of the way for games that require you to jump around.
Don't forget that those not playing on the big screen need to keep entertained too, and we don't mean just by your awesomeness at Call of Duty. Provide plenty of side entertainment such as a Foosball or Ping Pong table, and if you have the budget lots of classic arcade games on free play will pair perfectly with the high end gaming system on the big screen.
Have fun with the decor, whether it's a gaming theme or something totally out of the blue that your wife/girlfriend would never let in the main house but fits right on in in a game room. It's the one place in your house that you're allowed to let your inner child out and even show off that old Pez collection you've been trying to rationalize keeping.

Organized & Clean
Don't just let your games, controllers and accessories just lay around like a 6 year old's bedroom - we're better (and older) than that! Make a proper place for everything and store and organize all your stuff. Keep everything clean and dust free, especially your electronics that need to breathe to operate maintenance free (remember the days of blowing on our Nintendo cartridges?).
There's probably a good chance that your buddies aren't going to use coasters, so go for maintenance free furniture that can simply wipe clean after everyone leaves and no one offers to help clean up. If you keep lots of coasters around though it'll provide a nice little hint and people are more likely to use them if they are conveniently on hand. Keep lots of napkins and trash cans nearby as well, plus recycling bins if you're into saving the environment (which you should be).
