We have tried tourneys in the past with no success. But if you guys are serious about this, we can even include prizes for the winning team.
1) Need to plan it out well. Rules, Date and Time, Teams, Prizes, etc.
2) Need to have the commitment of all who plan on participating. No bailing at the last minute, if you don't think you can make it, don't sign up for it at all. Maybe have a mandatory deposit or buy in fee so that people are more likely to stay committed ($5 or $10 per person). If it is a deposit, it will be refunded to your paypal account after the tourney. If it is a buy-in, the money will be used for prizes.
3) We can set up an additional Scrim server(s) just for the event so that we can have multiple scrims going on at the same time, in which case we can go through the tourney a lot faster. It can all take place in one day.
Let us know.
