I think part of it might be that different people who are running forum battles have differing levels of adherence to the rules/level of fudge.
There's people like you who stick to the rules pretty consistently.
Then there's people like me(and most others) who stick to some rules, but not others (I.E. movements can be fudged, weapons and skill capabilities can't)
And then there's people like warhead who are willing to fudge virtually everything, so long as it's awesome.
Those are some pretty vague references, but I'm sure you are getting the picture. Depending on the person who is running the game, "Brikwars" could be any number of different games with different rules, so this is sort of to be expected.
My way of dealing with this was as follows; In krysto, somebody had said that they wanted to self-destruct a vehicle,or maybe it was even one of the buildings, but there weren't any pbb buttons for self-destruction or even any explosives anywhere near any of the player's figs.... Therefore that player just did whatever his orders for the last turn were all over again. Looking back at that battle, that player didn't do very well. Therefore, a bit o' advice:
rather than simply ignoring "impossible" orders, have the player's figs attempt to do whatever it was that they were ordered to do even though they can't actually do it. (I.E. for the ninjas, they give up their movements to sprint to complete as much of their orders as possible. For the self destruct thing, the figs search around the field for some explosives so that they can build their own self-destruct function.) This way, the players will end up less angry at you for "ignoring their orders", while at the same time making the game rather humorous as we all watch them fail miserably. 2 cents has been given.
Anywhore, this turn is looking excellent so fa,just as all the others, hopefully the people who didn't send in orders will get on it soon.
