Quoted from DNO:NO double gaming!....
If you’re playing a 4 player over here, don’t go start playing something else between turns.
This is not a bad thing in our circles. If you are doing it right, there is no problem with double gaming, you just need a double game partner. My brother and I do it all the time when playing at shows. It just requires picking the primary game and switching off when its your turn on the main game. Or if your on the secondary machine and are kicking ass, you pass your turn on to your partner on the primary. Nobody has to wait, but the swap has to happen instantly even if you drain your ball on the secondary game. To the people around you it is no different than me playing the first solo and my brother playing the second solo. Both machines are being played, but by two people at once. This saves a boatload of time when there are literally hundreds of machines to get around to playing... and I don't begrudge anyone else doing this either, but when ball three on the last player is over, you give up the machine if people are waiting. And if people are waiting, I will always ask them to join us if we have an unused player. If they refuse to play multiple players, then thats when I don't mind making them wait, even if we play a couple of games, because they could join us and have fun at any time, then play it solo when we finish, or they can stand there, arms crossed, looking pissed until we finish. If you are one of those people, you have my pity, but not my sympathy.
