There will be no rules on dice at this tournament. I don't think this has ever featured on the UK scene. If I was feeling particularly evil I'd insist the the dice from the original game are used (most still have them, nerds that we are) as the rules seem to explicitly suggest that they are the dice that should be used. But no, none of that, use whatever dice you like. I prefer four sided dice in my games.
And on the issue of food, the tournament venue is already sorted, the wonderful Headlands Hotel in Blackpool which is run, slightly ironically by a German chap called Charles Ruppert who runs the finest bed and breakfast in the land in my experience with the most wonderful food menu,
The only thought I've had is whether, unlike other tourneys, that we take this around the country year on year to different towns and cities. A sort of 'British Open'. But, the venue is so good, and ticks so many boxes, that I think this unlikely.
