Government control?

I disagree with this reasoning completely. Consider this, you enter a room with ten people in the room. Eight out of the ten people play nothing but Game A, you come into the room to play Game B, and the other newcomer wants to play a Game C. There can only be one game played at a time and it requires at least six out of the ten people in the room in order to agree that they want to play it. What's the most effective method of getting people in Game A to remotely consider playing into your game?

...Wait for them to get bored of game A then suggest game B? I don't know. From what I've seen at the few LANWars I've been to, people keep playing their game the whole duration and ignore everyone that doesn't want to play it with them, leaving tiny fragmented groups of people playing MMOs ranging from flavor of the month (SWTOR at the time) to completely dead (Age of Conan private server, what the pineapple?) while the majority play LoL the entire time.
