Is it ever a good idea to start campaign with an adventure?
I have played many campaigns where DM did not disclouse some improtant information to the players at the beginning of the campaign, because he wanted it to be "an adventure."
Once, he didn't tell us we will travel 50 miles into the forest.
Another, that the plot requires us to make a moral choice (not for real life, but still a moral choice).
One time our characters were just drinking in a tavern, when suddenly an old wizard came in and sent us on a quest.
Also, when I told the DM my character is the greatest swordsman in the world and I kill the BBEG, he made me start rolling dice for some reason? Also he said I missed, which I didn't agree to.
There were other instances as well, but what unites them all is the fact that it never, ever worked out. Players have been prepared and excited for a specific plot that they wrote into the backstory for their super special OC main character and then lost it all to a sudden thing they couldn't see coming, like the plot of the actual adventure the DM prepared. This taught me to never make plots in my campaigns. I just ask the players what should happen.
I wonder however, if it's always the case. Do you have similar experience? Have you ever done or prepared an adventure and it worked out well?
