Limited Editions and a Bit of a Moan

[Berf]

Yes, I see your problem (your dice problem, that is ).
Seriously though, if time is your main issue, let me assure you that an Eden tournament can be played very efficiently. A regular one (betwenn 12 and 16 players) fits in a day without problem. One game is time-limited at 1h30, so you can play 4 games in about 6 hours. And since we play on little field, it doesn't require a very large place. Lastly, since each player is self-sufficient - Mission-wise and we usually don't allow to change the troop between games - the organisator(s) only need to act as referee and match the players after each game.
Honestly, it is very simple and very fast. I don't want to force you to organize one, but just so you know it is far less hassle than any other game I've played in tournaments
