I am thinking about entering a tourement next year and I have some questions.

Are they very strict(house rules, point limit etc)?

I havent really played a full game of Warhammer or 40k in months. How prepared do you have to be?
Do U play the same type of mission or sernario all the time ( clense or pittced battle) or do they do different ones?
Have you met a really anal, serious player?

Vets and tourney players feedback welcome...(duhh)

I dont play tourny but I have seen several.

yes.

Very.
No.
Tons.

WEll it depends on WHAT tourney you want to get into, any GW one is going to be serious, but a simple tourney at your local Rogue Trader might not be so strictr and it may Even be a "Fun" tourney.
