Ill.
first, everyone on all sides were unclear what you mean.
second, my "system" is not that complicated.
third, I did not get an attitude, though I am critical of yout response. it does not require one to have an attitude to be critical of you not even trying to make youself clear, but still telling us we do not understand what you mean. We have been guessing for 2 pages, and as of yet, I have not seen you either explain how what any of us have posted is not what you mean in what way, specifically. It would of been easier if you just made yourself clear. you say rolling a die (implemented) would be too complicated, but even now there is the question on rather you mean just for yourself to see, or some sort of group thing.
do you realize the game already had die rolls? want a coin flip, try "/roll 1 2"
if you want a simple yes or no, why not put an odds that you think is fair, and /roll 1/100 and that would make it a percentage yes, rest = no. maybe that is easier for you to see? Or you can keep a penny near your computer and do it old school?
it almost sounds like you want to automate RP, but I am sure I must be reading more into that. I would like to see more player interaction, I dont need the NPCs of Hyldaa to Rp so much they decide they dont need us visitors, eh?
so if rolling a /roll 1 100 and having preset outcomes is too complicated for you, maybe decide what the rolls mean after you roll?

either way, it is simpler than rolling a die Ingame (already implemented) that allows you to, among yourself or small groups determine certain behavior that your character will interact with others, I will respond to that.
I see some value in having a system. nothing stinks more than tossing a pie and having everyone ducking it every time. Same with kids playing. everyone wants to control and win the 'game'. find people who will actually let themselves be hit in the face once in a while.. then maybe even '/me keeps an eye on you every time you pick something up'... and just ignore the godmoders who never get dirty in a foodfight. you will find these same people would not agree that they will be hit in the face even 5% of the time. That is why you can find me on ezpcusa.
Zanzibar, thanks for deciphering it, but I am still unclear whether it would always be 50/50 or what. if so maybe they mean something like /try like "/try to throw a pie at baughb" which woudl show up as "Bamko tries to throw a pie at Baughb but fails (or and hits him)? I would want a percentage. but it would still meet resistance I predict, from those I mentioned above. (I should get a bonus for agility, I was watching, I cast defensive wind, I declare my dodge on you!) but at least I think I understand the proposal now.
I think find people who will RP without being teflonic (is that a word?). ones who can not let their avatar get dirty, well, ostracize them?
gtg,... hope that is clear enough both on my views and on my suggestions.
