Well I forgot to mention how fun those looked.
On Iricia, I held a few melee only rounds. It made the players work as a team. But after one of the rounds lasted for 30 minutes, they started to get annouyed (The round just wouldn't end!).
Then I held a few Gwars Events, Setting the weapons to blaster's only. And that looked fun. 30 players just running around with blasters
.
Then I tried a Spar Tournament, but we need a few more commands, so things don't get so confusing, like they were.
