You better make sure there's room for all your guests to gather around the TV. If the couches and recliners aren't going to seat everyone, drag out the kitchen's chairs, the fold out chairs, and beanbags if you've got them. Nobody wants to stand during a 4 hour game, while everyone else is sitting around. If you to have to run to the store to buy some lawn chairs - do it. Or if you have to borrow chairs from a friend, make sure that everyone can comfortably sit around the TV, and that no one has their view obstructed; might as well have that person sit in the floor like a 3-year-old.
