I'm fond of: Grab a game, put it on the table and start setting up and playing. If other people join you, so much the better.
I'm a fan of this approach as well. Less talking, more action. Pick one unilaterally and go. Sometimes a game gets taken out and put away without playing it, but at least it gets the ball rolling.
In the end what game you play with a large group really doesn't matter THAT much. No need to debate endlessly.
