Yes definately, this is why we had a 'low' turnout, we usually draw 20 or so, but we made sure in the rules that it was 1750 of stuff other people would use, with a sense of common decency- i.e if you break something, you tell them and fix it or provide them with things to do so. we were lucky in that there were no breakages.
Another idea you could toy with to add in the 'random' aspect is the idea of in-house strategem style cards.
these could work in one of 2 ways, either each player gets one for the tournament, or a week in advance by random or you get 6, one for each game.
For example...
Elite Army- This army is considered 'elite' and thus Elite units count as scoring units for this game
Mechanised-All vehicles receive a free 15 points of upgrades if they have a transport capacity (this may not be spent on upgrading weapons, with the exception of hunter killer missles, i.e may not be spent on extra sponsons etc)
Hero-This army is joined by a hero, nominate one independent character- for this battle, the leadership of this character is increased by one (to a maximum of 10), additionally all models within 12 inches may use this characters
Ld for all tests. If this is used on a character who is already
Ld 10, increase this to 16 inches.
Veterans- Nominate one troops unit, this unit receieves +1
Ws OR
Bs for this battle (this is done BEFORE blobbing/combat squadding to stop abuse of 50 man guard squads at ws4)
Fast Deployment- Any unit which counts as a 'fast attack' choice may ALWAYS outflank in this battle.
Lay of the Land-All units in this army have been extensively briefed on the terrain for this battlefield, and thus may roll an extra dice when moving through cover.
These are just some suggestions, what you then do is say that each general may have 6 lists associated with each strategem and may use each list one time (you must number each list and put on the game card which list you use) What this means is people have to think about the missions (which would also be specially written) and decide which strategem to use.
What this does is a number of things
1/ people bring along a variety in lists- without having to bring 6 different armies with them, as ideally all these armies will be similar, with just minor tweaks, i.e in a
meq list, you may see an extra squad of guardsmen, because the 4 chimeras who had bought extra armour are now cheaper, or people will squeeze an extra elites unit in, because they are scoring-but the fundamental structure stays the same.
2/ brings in a third dimension (the first 2 being battle plan and luck)
3/ people have fun because they are doing things they may not do, and can engage in the fluff of their army
4/ this may sound contrived, but i am big on fluff, hence my entire 2500 catachan army is owned by Dakka members who each 'own' one model, but one thing that strikes me about
40k is that the armies often seem so small and insignificant, this way, if you add together the 6 armies, as they would theoretically be different contingents, it would look good.
5/ and lastly atleast 1 person will bring seperate models for each list, and this will look awesome.
again, ideas i am coming up with.
as for hidden missions, i think the tournament host should be counted as a trusted figure who wouldn't let people in on the missions, as i think knowing the missions before hand does remove a tactical and fluffy element.
i always had an idea for a mission where one player would be an 'ambusher' and the other a 'defender' the defender would have a certain amount points more than the ambusher, but the ambusher would be given nothing, and would label his/her units with numbers, then on a diagram of the board, label a piece of terrain for each unit to be put in, which would pop up as reserves on a regular roll, but act normally. this would be played on a long table, as in from short edge to short edge, and operate on a 'kill points' system, except the ambusher is awarded kill points for the amount of units they kill and deducted one for every unit that makes it (with atleast 25% strength) to the other board edge, then say +/-3 points = minor win/loss etc etc
some random musings, which have gone on far too long, i am in tourney making mood now
